Features and Benefits

  • Accommodates Multiple Op-Amp Configurations
  • On-Board LED Driver
  • Accommodates Multiple Wavelength LEDs
  • Proven PCB Layout
  • Fully Assembled and Tested

Product Details

The MAX9636 evaluation kit (EV kit) is an assembled and tested PCB used to evaluate the MAX9636 low-power, low-noise, CMOS input op amp, which is suitable for photodiode transimpedance front-ends in portable medical instruments. The EV kit is preconfigured for a transimpedance amplifier (TIA). Additionally, an on-board LED driver circuit provides a controlled light source to help evaluate the performance of the MAX9636 TIA circuit. The EV kit can easily be adapted to act as noninverting, inverting, or differential amplifier by changing a few components. Another EV kit is offered for the MAX9638 dual version of this op amp to enable evaluation in an active filter circuit configuration.

The EV kit comes with a MAX9636AXT+ installed.

Applications

  • Battery-Powered Devices
  • Notebooks
  • Portable Media Players
  • Smoke Detectors
