Description
The TS472 is a differential-input microphone
preamplifier optimized for high-performance, PDA
and notebook audio systems.
This device features an adjustable gain from 0dB
to 40dB with excellent power-supply and
common-mode rejection ratios. In addition, the
TS472 has a very low-noise microphone bias
generator of 2V.
It also includes a complete shutdown function,
with active low standby mode.
Applications
■
Video and photo cameras with sound input
■
Sound acquisition & voice recognition
■
Video conference systems
■
Notebook computers and PDAs
