MAX9632 Evaluation Kit

General Description

The MAX9632 evaluation kit (EV kit) provides a proven

design to evaluate the MAX9632 low-noise, precision

and wide-band op amp. The MAX9632 can be used in a

wide variety of applications such as test and measure-

ment, instrumentation, medical imaging, control loops,

and professional audio. Because of the ultra-low noise

and great precision, it can either drive high-resolution

(18 to 24 bits) ADCs or buffer high-resolution DACs. The

EV kit circuit can easily be adapted by installing shunts

and changing a few components to support multiple

op-amp configurations: transimpedance, noninverting,

inverting, or differential 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 single-supply voltage from +4.5V to +36V or a

dual-supply voltage from Q2.25V to Q18V.

MAX9632 Evaluation Kit Evaluates: MAX9632 Quick Start • MAX9632 EV kit Required Equipment • ±15V, 40mA DC power supply (PS1) • +1V precision voltage source • Digital multimeter (DMM) Procedure The EV kit is fully assembled and tested. Follow the steps below to verify board operation: 1) Connect the positive terminal of the +15V supply to the VCC pad and the GND terminal to the GND pad. Connect the negative terminal of the -15V supply to the VEE pad and the GND terminal to the GND pad.
