The MAX4062EUB+ is a differential microphone preamplifier with internal bias in 10 pin μMAX package. It is a differential-input microphone preamplifier optimized for notebook and PDA audio systems. This device features adjustable gain with excellent power-supply rejection and common- mode rejection ratios, making them ideal for low noise applications in portable audio systems. The MAX4062 are capable of switching their output between the differential input and a single ended auxiliary microphone amplifier input. In addition, the MAX4062 has a low noise microphone bias generator. The differential gain of the MAX4062 is set with a single resistor.
Supply voltage range is 2.4V to 5.5V
Operating temperature range from -40°C to 85°C
High PSRR is 86dB at 1KHz and high CMRR is 70dB at 1KHz
