General Description

The MAX9812/MAX9813 are single/dual-input, 20dB fixed-gain microphone amplifiers. They offer tiny packaging and a low-noise, integrated microphone bias, making them ideal for portable audio applications such as notebook computers, cell phones, and PDAs. These amplifiers feature a 500kHz bandwidth, rail-to-rail out puts, an industry-leading 100dB power-supply rejection ratio, and a very low 0.015 THD+N. Power-saving features include very low 230μA supply current and a total shutdown mode that cuts the combined supply and BIAS currents to only 100nA.
