Descriptions:
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.
