Audio Amp Microphone 1-CH Mono Class-AB 24-Pin QFN T/R, TS472IQT, STMicroelectronics

The TS472 is a differential-input microphone preamplifier optimized for high-performance PDA and notebook audio systems.This device features an adjustable gain from 0 to 40 dB with excellent power-supply and commonmode rejection ratios. In addition, the TS472 has a very low noise microphone bias generator of 2 V.It also includes a complete shutdown function, with active low standby mode.

Low noise: 10 nV/vHz typ. equivalent input noise at F = 1 kHz

Fully-differential input/output

2.2 to 5.5 V single supply operation

Low power consumption at 20 dB: 1.8 mA

Fast start up time at 0 dB: 5 ms typ.

Low distortion: 0.1% typ.

40 kHz bandwidth regardless of the gain

Active low standby mode function (1 µA max)

Low noise 2.0 V microphone bias output

Available in flip-chip lead-free package and in QFN24 4 x 4 mm package

ESD protection (2 kV)
