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.
