MAX9813 Datasheet | Maxim Integrated

Description The MAX9812/MAX9813 are single/dual-input, 20d B 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 puters, cell phones, and PDAs. These amplifiers feature a 500k Hz bandwidth, rail-to-rail outputs, an industry-leading 100d B 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 bined supply and BIAS currents to only 100n A. The MAX9812 is a single amplifier in a 6-pin SC70 package (2mm x 2.1mm) and the MAX9813 is a dualinput amplifier available in an 8-pin SOT23 (3mm x 3mm) package. The MAX9813 has two inputs allowing two microphones to be multiplexed to a single output. The MAX9812/MAX9813 are offered in two grades. The MAX9812L/MAX981...
