MAX9813LEKA+T

MAXIM INTEGRATED PRODUCTS  MAX9813LEKA+T  音频功率放大器, 固定增益, 2通道, 2.7V 至 3.6V, SOT-23, 8 引脚

The is a low cost, dual input, fixed gain microphone amplifier with integrated bias in 8 pin SOT-23 package. It has low noise, integrated microphone bias and tiny packaging making it ideal for portable audio applications such as notebook computers, cell phones and PDAs. This amplifier features a 500KHz bandwidth, rail to rail outputs, an industry leading 100dB power supply rejection ratio and a very low 0.015% THD+N. The device includes very low 230µA supply current and a total shutdown mode that cuts the combined supply and BIAS currents to only 100nA. The MAX9813 has two inputs allowing two microphones to be multiplexed to a single output.
