Data Sheet April 13, 2007 FN6156.2
Single and Dual Ultra-Low Noise, Rail-to-Rail, Op Amp
The ISL28191 and ISL28291 are tiny single and dual ultra-low noise, ultra-low distortion operational amplifiers. Fully specified to operated down to +3V single supply. These amplifiers have outputs that swing rail-to-rail, and an input common mode voltage that extends to ground (ground sensing). The ISL28191 and ISL28291 are unity gain stable with an input referred voltage noise of 1.7nV/Hz. Both parts feature 2nd and 3rd harmonic distortion of -76dBc and -70dBc, respectively. The ISL28191 is available in the space-saving 6 Ld TDFN (1.6mm x 1.6mm) and SOT-23 packages. The ISL28291 is available in the 10 Ld TQFN (1.8mm x 1.4mm) and MSOP packages. All devices are guaranteed over -40C to +125C.

ISL28191, ISL28291 Applications Information
Product Description
The ISL28191 and ISL28291 are voltage feedback operational amplifier designed for communication and imaging applications requiring very low voltage and current noise. Both parts feature low distortion while drawing moderately low supply current. The ISL28191 and ISL28291 use a classical voltage-feedback topology which allows them to be used in a variety of applications where current-feedback amplifiers are not appropriate because of restrictions placed upon the feedback element used with the amplifier. the output to the negative input and ground the positive input (as shown in Figure 26).

FIGURE 26. PREVENTING OSCILLATIONS IN UNUSED CHANNELS
Current Limiting
The ISL28191 and ISL28291 have no internal currentlimiting circuitry. If the output is shorted, it is possible to exceed the Absolute Maximum Rating for output current or power dissipation, potentially resulting in the destruction of the device. This is why output short circuit current is specified and tested with RL = 10.
Enable/Power-Down
The ISL28191 and ISL28291 amplifiers are disabled by applying a voltage greater than 2V to the ENABLE pin, with respect to the V- pin. In this condition, the output(s) will be in a high impedance state and the amplifier(s) current will be reduced to 13A/Amp. By disabling the part, multiple parts can be connected together as a MUX. The outputs are tied together in parallel and a channel can be selected by the ENABLE pin. The ENABLE pin also has an internal pull down. If left open, the ENABLE pin will pull to the negative rail and the device will be enabled by default.
Power Dissipation
It is possible to exceed the +125C maximum junction temperatures under certain load and power-supply conditions. It is therefore important to calculate the maximum junction temperature (TJMAX) for all applications to determine if power supply voltages, load conditions, or package type need to be modified to remain in the safe operating area. These parameters are related as follows:
T JMAX = T MAX + ( JA xPD MAXTOTAL )
Input Protection
All input terminals have internal ESD protection diodes to both positive and negative supply rails, limiting the input voltage to within one diode beyond the supply rails. Both parts have additional back-to-back diodes across the input terminals (as shown in Figure 25). In pulse applications where the input Slew Rate exceeds the Slew Rate of the amplifier, the possibility exists for the input protection diodes to become forward biased. This can cause excessive input current and distortion at the outputs. If overdriving the inputs is necessary, the external input current must never exceed 5mA. An external series resistor may be used to limit the current as shown in Figure 25.
R +
where: * PDMAXTOTAL is the sum of the maximum power dissipation of each amplifier in the package (PDMAX) * PDMAX for each amplifier can be calculated as follows:
V OUTMAX PD MAX = 2*V S x I SMAX + ( V S - V OUTMAX ) x --------------------------R
L
where: * TMAX = Maximum ambient temperature * JA = Thermal resistance of the package * PDMAX = Maximum power dissipation of 1 amplifier * VS = Supply voltage * IMAX = Maximum supply current of 1 amplifier * VOUTMAX = Maximum output voltage swing of the application * RL = Load resistance
FIGURE 25. LIMITING THE INPUT CURRENT TO LESS THAN 5mA
Using Only One Channel
The ISL28291 is a Dual channel op-amp. If the application only requires one channel when using the ISL28291, the user must configure the unused channel to prevent it from oscillating. Oscillation can occur if the input and output pins are floating. This will result in higher than expected supply currents and possible noise injection into the channel being used. The proper way to prevent this oscillation is to short

Power Supply Bypassing and Printed Circuit Board Layout
As with any high frequency device, good printed circuit board layout is necessary for optimum performance. Low impedance ground plane construction is essential. Surface mount components are recommended, but if leaded components are used, lead lengths should be as short as possible. The power supply pins must be well bypassed to reduce the risk of oscillation. The combination of a 4.7F tantalum capacitor in parallel with a 0.01F capacitor has been shown to work well when placed at each supply pin. For good AC performance, parasitic capacitance should be kept to a minimum, especially at the inverting input. When ground plane construction is used, it should be removed from the area near the inverting input to minimize any stray capacitance at that node. Carbon or Metal-Film resistors are acceptable with the Metal-Film resistors giving slightly less peaking and bandwidth because of additional series inductance. Use of sockets, particularly for the SO package, should be avoided if possible. Sockets add parasitic inductance and capacitance which will result in additional peaking and overshoot.
