The MAX9636/MAX9637/MAX9638 are single-supply, CMOS input op amps featuring wide bandwidth at low quiescent current, making them suitable for a broad range of battery-powered applications such as portable medical instruments, portable media players, and smoke detectors. A combination of extremely low input bias currents, low input current noise and low input voltage noise allows interface to high-impedance sources such as photodiode and piezoelectric sensors.

The ICs feature a maximized ratio of gain bandwidth (GBW) to supply current. The devices operate from a single 2.1V to 5.5V supply at a typical quiescent supply current of 36µA. For additional power conservation, the MAX9636 and MAX9638 offer a low-power shutdown mode that reduces supply current to 1µA and places the amplifiers' outputs into a high-impedance state.

The ICs are specified over the automotive operating temperature range (-40°C to +125°C). The single is offered in a space-saving, 6-pin SC70 package, while the dual is offered in tiny, 8-pin SC70 and 10-pin UTQFN packages.

Applications

  • Battery-Powered Devices
  • Piezoelectric Transducer Amplifiers
  • Portable Medical Instruments
  • Smoke Detectors
  • Tablets
  • Transimpedance Amplifiers

Features and Benefits

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

Product Detail

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
