GENERAL DESCRIPTION
The ADR380 and ADR381 are precision 2.048 V and 2.500 V band gap voltage references featuring high accuracy, high stability, and low-power consumption in a tiny footprint. Patented temperature drift curvature correction techniques minimize nonlinearity of the voltage change with temperature. The wide operating range and low power consumption make them ideal for 3 V to 5 V battery-powered applications. The ADR380 and ADR381 are micropower, low dropout voltage (LDV) devices that provide a stable output voltage from supplies as low as 300 mV above the output voltage. They are specified over the industrial (-40C to +85C) temperature range. ADR380/ADR381 is available in the tiny 3-lead SOT-23 package.

PARAMETER DEFINITIONS Temperature Coefficient Long-Term Stability
The change of output voltage over the operating temperature change and normalized by the output voltage at 25C, expressed in ppm/C. The equation follows:
TCVO [ ppm / C ] = VO (25C ) x (T2 - T1 ) VO (T2 ) - VO (T1 ) x 106
A typical shift in output voltage over 1,000 hours at a controlled temperature. The graphs TPC 24 and TPC 25 show a sample of parts measured at different intervals in a controlled environment of 50C for 1,000 hours.
VO = VO (t0 ) -VO (t1 ) VO [ ppm ] = VO (t0 ) -VO (t1 ) VO (t0 ) x 106
where: VO (25C) = VO at 25C. VO (T1) = VO at Temperature 1. VO (T2) = VO at Temperature 2.
Line Regulation
where: VO (t0) = VO at Time 0. VO (t1) = VO after 1,000 hours' operation at a controlled temperature. Note that 50C was chosen since most applications we have experienced run at a higher temperature than 25C.
Thermal Hysteresis
The change in output voltage due to a specified change in input voltage. It includes the effects of self-heating. Line regulation is expressed in either percent per volt, parts-per-million per volt, or microvolts per volt change in input voltage.
Load Regulation
The change in output voltage due to a specified change in load current. It includes the effects of self-heating. Load regulation is expressed in either microvolts per milliampere, parts-permillion per milliampere, or ohms of dc output resistance.
The change of output voltage after the device is cycled through temperature from +25C to -40C to +85C and back to +25C. This is a typical value from a sample of parts put through such a cycle.
VO_HYS = VO (25C ) - VO_TC VO_HYS [ ppm ] = VO (25C ) - VO_TC VO (25C ) x 106
where: VO (25C) = VO at 25C. VO_TC = VO at 25C after temperature cycle at +25C to -40C to +85C and back to +25C.

THEORY OF OPERATION
Band gap references are the high performance solution for low supply voltage and low power voltage reference applications, and the ADR380/ADR381 are no exception. But the uniqueness of this product lies in its architecture. By observing Figure 1, the ideal zero TC band gap voltage is referenced to the output, not to ground. The band gap cell consists of the PNP pair Q51 and Q52, running at unequal current densities. The difference in VBE results in a voltage with a positive TC which is amplified up by the ratio of 2 x R58/R54. This PTAT voltage, combined with VBEs of Q51 and Q52, produce the stable band gap voltage. Reduction in the band gap curvature is performed by the ratio of the two resistors R44 and R59. Precision laser trimming and other patented circuit techniques are used to further enhance the drift performance.

degrade by putting an output capacitor here is turn-on time. (This will vary depending on the size of the capacitor.) Load transient response is also improved with an output capacitor. A capacitor will act as a source of stored energy for a sudden increase in load current.
APPLICATIONS Stacking Reference ICs for Arbitrary Outputs
Some applications may require two reference voltage sources which are a combined sum of standard outputs. The following circuit shows how this stacked output reference can be implemented:

Device Power Dissipation Considerations
The ADR380/ADR381 are capable of delivering load currents to 5 mA with an input voltage that ranges from 2.8 V (ADR381 only) to 15 V. When this device is used in applications with large input voltages, care should be taken to avoid exceeding the specified maximum power dissipation or junction temperature that could result in premature device failure. The following formula should be used to calculate a device's maximum junction temperature or dissipation: PD = TJ - TA JA
Two ADR380s or ADR381s are used; the outputs of the individual references are simply cascaded to reduce the supply current. Such configuration provides two output voltages-- VOUT1 and VOUT2. VOUT1 is the terminal voltage of U1, while VOUT2 is the sum of this voltage and the terminal voltage of U2. U1 and U2 can be chosen for the two different voltages that supply the required outputs. While this concept is simple, a precaution is in order. Since the lower reference circuit must sink a small bias current from U2, plus the base current from the series PNP output transistor in U2, the external load of either U1 or R1 must provide a path for this current. If the U1 minimum load is not well-defined, the resistor R1 should be used, set to a value that will conservatively pass 600 A of current with the applicable VOUT1 across it. Note that the two U1 and U2 reference circuits are locally treated as macrocells, each having its own bypasses at input and output for optimum stability. Both U1 and U2 in this circuit can source dc currents up to their full rating. The minimum input voltage, VS, is determined by the sum of the outputs, VOUT2, plus the 300 mV dropout voltage of U2.

where: PD is the device power dissipation, TJ and TA are junction and ambient temperatures, respectively, and JA is the device package thermal resistance.
Input Capacitor
Input capacitor is not required on the ADR380/ADR381. There is no limit for the value of the capacitor used on the input, but a capacitor on the input will improve transient response in applications where the load current suddenly increases.
Output Capacitor
The ADR380/ADR381 do not need an output capacitor for stability under any load condition. An output capacitor, typically 0.1 F, will take out any very low level noise voltage, and will not affect the operation of the part. The only parameter that will
In many current-output CMOS DAC applications where the output signal voltage must be of the same polarity as the reference voltage, it is often required to reconfigure a current-switching DAC into a voltage-switching DAC through the use of a 1.25 V reference, an op amp, and a pair of resistors. Using a currentswitching DAC directly requires an additional operational amplifier at the output to reinvert the signal. A negative voltage

reference is then desirable from the point that an additional operational amplifier is not required for either reinversion (current-switching mode) or amplification (voltage-switching mode) of the DAC output voltage. In general, any positive voltage reference can be converted into a negative voltage reference through the use of an operational amplifier and a pair of matched resistors in an inverting configuration. The disadvantage to this approach is that the largest single source of error in the circuit is the relative matching of the resistors used. The circuit in Figure 3 avoids the need for tightly matched resistors with the use of an active integrator circuit. In this circuit, the output of the voltage reference provides the input drive for the integrator. The integrator, to maintain circuit equilibrium, adjusts its output to establish the proper relationship between the reference's VOUT and GND. Thus, any negative output voltage desired can be chosen by simply substituting for the appropriate reference IC. A precaution should be noted with this approach: although rail-to-rail output amplifiers work best in the application, these operational amplifiers require a finite amount (mV) of headroom when required to provide any load current. The choice for the circuit's negative supply should take this issue into account.

Precision High Current Voltage Source
In some cases, the user may want higher output current delivered to a load and still achieve better than 0.5% accuracy out of the ADR380/ADR381. The accuracy for a reference is normally specified on the data sheet with no load. However, the output voltage changes with load current. The circuit in Figure 5 provides high current without compromising the accuracy of the ADR380/ADR381. By op amp action, VO follows VREF with very low drop in R1. To maintain circuit equilibrium, the op amp also drives the N-Ch MOSFET Q1 into saturation to maintain the current needed at different loads. R2 is optional to prevent oscillation at Q1. In such an approach, hundreds of milliamps of load current can be achieved and the current is limited by the thermal limitation of Q1. VIN = VO + 300 mV.

Many times in low power applications, the need arises for a precision current source that can operate on low supply voltages. As shown in Figure 4, the ADR380/ADR381 can be configured as a precision current source. The circuit configuration illustrated is a floating current source with a grounded load. The reference's output voltage is bootstrapped across RSET (R1 + P1), which sets the output current into the load. With this configuration, circuit precision is maintained for load currents in the range from the reference's supply current, typically 90 A to approximately 5 mA.
