MAX9633 Evaluation Kit

General Description

The MAX9633 evaluation kit (EV kit) provides a proven

design to evaluate the MAX9633 dual, low-noise, low-

distortion op amp that is optimized to drive ADCs

for use in applications from DC to a few MHz. The

exceptionally fast settling time and low input offset

voltage make the device an excellent solution to drive

high-resolution 12-bit to 18-bit SAR ADCs. The EV kit

circuit is configured as a unity-gain buffer, but can

easily be adapted by installing shunts and changing a

few components to support multiple op-amp configura-

tions: transimpedance, noninverting, inverting, or differ-

ential amplifier. The components on the EV kit have pads

that accommodate 0805 packages, making them easy to

solder and replace. The EV kit accepts a +4.5V to +36V

single-supply voltage, or a Q2.25V to Q18V dual-supply

voltage.

MAX9633 Evaluation Kit Evaluates: MAX9633 and INB- pads. Install a shunt on JU3 to ground the INBinput in this configuration. The output voltage is given by the following equation:  R9  VOUT= 1 +  (VIN )  R7  Differential Amplifier To configure op-amp U1-A as a differential amplifier, replace R1–R4 with appropriate resistors and install a shunt on jumper JU1. Make sure R1 = R4 and R2 = R3.
