Single/Dual/Quad, 28MHz, Low-Noise, Low-Voltage, Precision Op Amps
General Description
The MAX410/MAX412/MAX414 single/dual/quad op amps set a new standard for noise performance in high-speed, low-voltage systems. Input voltage-noise density is guaranteed to be less than 2.4nV/Hz at 1kHz. A unique design not only combines low noise with 5V operation, but also consumes 2.5mA supply current per amplifier. Low-voltage operation is guaranteed with an output voltage swing of 7.3VP-P into 2k from 5V supplies. The MAX410/MAX412/MAX414 also operate from supply voltages between 2.4V and 5V for greater supply flexibility. Unity-gain stability, 28MHz bandwidth, and 4.5V/s slew rate ensure low-noise performance in a wide variety of wideband and measurement applications. The MAX410/MAX412/MAX414 are available in DIP and SO packages in the industry-standard single/dual/quad op amp pin configurations. The single comes in an ultrasmall TDFN package (3mm 3mm). 2.5mA Supply Current Per Amplifier Low Supply Voltage Operation: 2.4V to 5V 28MHz Unity-Gain Bandwidth 4.5V/s Slew Rate 250V (max) Offset Voltage (MAX410/MAX412) 115dB (min) Voltage Gain Available in an Ultra-Small TDFN Package

Note 1: The amplifier inputs are connected by internal back-to-back clamp diodes. In order to minimize noise in the input stage, currentlimiting resistors are not used. If differential input voltages exceeding 1.0V are applied, limit input current to 20mA.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Applications Information
The MAX410/MAX412/MAX414 provide low voltagenoise performance. Obtaining low voltage noise from a bipolar op amp requires high collector currents in the input stage, since voltage noise is inversely proportional to the square root of the input stage collector current. However, op amp current noise is proportional to the square root of the input stage collector current, and the input bias current is proportional to the input stage collector current. Therefore, to obtain optimum low-noise performance, DC accuracy, and AC stability, minimize the value of the feedback and source resistance. becomes the dominant term, eventually making the voltage noise contribution from the MAX410/MAX412/ MAX414 negligible. As the source resistance is further increased, current noise becomes dominant. For example, when the equivalent source resistance is greater than 3k at 1kHz, the current noise component is larger than the resistor noise. The graph of Total Noise Density vs. Matched Source Resistance in the Typical Operating Characteristics shows this phenomenon. Optimal MAX410/MAX412/MAX414 noise performance and minimal total noise achieved with an equivalent source resistance of less than 10k.
MAX410/MAX412/MAX414
Total Noise Density vs. Source Resistance
The standard expression for the total input-referred noise of an op amp at a given frequency is: e t = en2 +(Rp +Rn )2 in2 + 4kT (Rp +Rn ) where: Rn = Inverting input effective series resistance Rp = Noninverting input effective series resistance en = Input voltage-noise density at the frequency of interest in = Input current-noise density at the frequency of interest T = Ambient temperature in Kelvin (K) k = 1.28 x 10-23 J/K (Boltzman's constant) In Figure 1, Rp = R3 and Rn = R1 || R2. In a real application, the output resistance of the source driving the input must be included with Rp and Rn. The following example demonstrates how to calculate the total output-noise density at a frequency of 1kHz for the MAX412 circuit in Figure 1. Gain = 1000 4kT at +25C = 1.64 x Rp = 100 Rn = 100 || 100k = 99.9 W en = 1.5nV/Hz at 1kHz in = 1.2pA/Hz at 1kHz et = [(1.5 x 10-9)2 + (100 + 99.9)2 (1.2 x 10-12)2 + (1.64 x 10-20) (100 + 99.9)]1/2 = 2.36nV/Hz at 1kHz Output noise density = (100)et = 2.36V/Hz at 1kHz. In general, the amplifier's voltage noise dominates with equivalent source resistances less than 200. As the equivalent source resistance increases, resistor noise 10-20
Voltage Noise Testing
RMS voltage-noise density is measured with the circuit shown in Figure 2, using the Quan Tech model 5173 noise analyzer, or equivalent. The voltage-noise density at 1kHz is sample tested on production units. When measuring op-amp voltage noise, only low-value, metal film resistors are used in the test fixture. The 0.1Hz to 10Hz peak-to-peak noise of the MAX410/MAX412/MAX414 is measured using the test

circuit shown in Figure 3. Figure 4 shows the frequency response of the circuit. The test time for the 0.1Hz to 10Hz noise measurement should be limited to 10 seconds, which has the effect of adding a second zero to the test circuit, providing increased attenuation for frequencies below 0.1Hz.

Input Protection
To protect amplifier inputs from excessive differential input voltages, most modern op amps contain input protection diodes and current-limiting resistors. These resistors increase the amplifier's input-referred noise. They have not been included in the MAX410/MAX412/ MAX414, to optimize noise performance. The MAX410/ MAX412/MAX414 do contain back-to-back input protection diodes which will protect the amplifier for differential input voltages of 0.1V. If the amplifier must be protected from higher differential input voltages, add external current-limiting resistors in series with the op amp inputs to limit the potential input current to less than 20mA.

Capacitive-Load Driving
Driving large capacitive loads increases the likelihood of oscillation in amplifier circuits. This is especially true for circuits with high loop gains, like voltage followers. The output impedance of the amplifier and a capacitive load form an RC network that adds a pole to the loop response. If the pole frequency is low enough, as when driving a large capacitive load, the circuit phase margin is degraded. In voltage follower circuits, the MAX410/MAX412/ MAX414 remain stable while driving capacitive loads as great as 3900pF (see Figures 6a and 6b).
When driving capacitive loads greater than 3900pF, add an output isolation resistor to the voltage follower circuit, as shown in Figure 7a. This resistor isolates the load capacitance from the amplifier output and restores the phase margin. Figure 7b is a photograph of the response of a MAX410/MAX412/MAX414 driving a 0.015F load with a 10 isolation resistor The capacitive-load driving performance of the MAX410/MAX412/MAX414 is plotted for closed-loop gains of -1V/V and -10V/V in the % Overshoot vs. Capacitive Load graph in the Typical Operating Characteristics. Feedback around the isolation resistor RI increases the accuracy at the capacitively loaded output (see Figure 8). The MAX410/MAX412/MAX414 are stable with a 0.01F load for the values of RI and CF shown. In general, for decreased closed-loop gain, increase RI or CF. To drive larger capacitive loads, increase the value of CF.

On TDFN packages, there is an exposed paddle that does not carry any current but should be connected to V- (not the GND plane) for rated power dissipation.
Total Supply Voltage Considerations
Although the MAX410/MAX412/MAX414 are specified with 5V power supplies, they are also capable of single-supply operation with voltages as low as 4.8V. The minimum input voltage range for normal amplifier operation is between V- + 1.5V and V+ - 1.5V. The minimum room-temperature output voltage range (with 2k load)
is between V+ - 1.4V and V- + 1.3V for total supply voltages between 4.8V and 10V. The output voltage range, referenced to the supply voltages, decreases slightly over temperature, as indicated in the 5V Electrical Characteristics tables. Operating characteristics at total supply, voltages of less than 10V are guaranteed by design and PSRR tests.
MAX410 Offset Voltage Null
The offset null circuit of Figure 9 provides approximately 450V of offset adjustment range, sufficient for zeroing offset over the full operating temperature range.
