MAX9632 Evaluation Kit Evaluates: MAX9632 General Description Features The MAX9632 evaluation kit (EV kit) provides a proven S Accommodates Multiple Op-Amp Configurations design to evaluate the MAX9632 low-noise, precision S +4.5V to +36V Wide Input Supply Range and wide-band op amp. The MAX9632 can be used in a S Shutdown Input wide variety of applications such as test and measure- S 0805 Components ment, instrumentation, medical imaging, control loops, and professional audio. Because of the ultra-low noise S Proven PCB Layout and great precision, it can either drive high-resolution S Fully Assembled and Tested (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 Ordering Information op-amp configurations: transimpedance, noninverting, inverting, or differential amplifier. The components on PART TYPE the EV kit have pads that accommodate 0805 packages, MAX9632EVKIT+ EV Kit making them easy to solder and replace. The EV kit +Denotes lead(Pb)-free and RoHS compliant. accepts a single-supply voltage from +4.5V to +36V or a dual-supply voltage from Q2.25V to Q18V.
