MAX9814EVKIT+ (MAXIM INTEGRATED PRODUCTS)

The MAX9814EVKIT+ from Maxim Integrated Products is an evaluation kit for MAX9814 microphone amplifier with AGC and low noise microphone bias. The MAX9814 low cost, high quality microphone amplifier is designed for single supply applications and features a low noise preamplifier, variable gain amplifier (VGA), output amplifier, microphone bias voltage generator and AGC control circuitry. The overall gain of the microphone amplifier is selectable to 40dB, 50dB or 60dB without compression. The MAX9814 incorporates compressor/limiter circuitry that limits the microphone output to a set voltage. The MAX9814 EV kit operates over a 2.7V to 5.5V range. The kit also features low quiescent current and shutdown control to minimize power consumption. The MAX9814 IC is available in a 14 pin TDFN (3mm x 3mm x 0.8mm) exposed paddle package.
