MAX9633 Evaluation Kit Evaluates: MAX9633 General Description Features The MAX9633 evaluation kit (EV kit) provides a proven S Accommodates Multiple Op-Amp Configurations design to evaluate the MAX9633 dual, low-noise, low- S +4.5V to +36V Wide Input Supply Range distortion op amp that is optimized to drive ADCs S 0805 Components for use in applications from DC to a few MHz. The S Proven PCB Layout exceptionally fast settling time and low input offset voltage make the device an excellent solution to drive S Fully Assembled and Tested 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 Ordering Information that accommodate 0805 packages, making them easy to PART TYPE solder and replace. The EV kit accepts a +4.5V to +36V MAX9633EVKIT+ EV Kit single-supply voltage, or a Q2.25V to Q18V dual-supply +Denotes lead(Pb)-free and RoHS compliant. voltage.
