8507
4mA COMPANDER
DESCRIPTION
LINEAR INTEGRATED CIRCUIT
The UTC
8507
is a automatic gain control system that is
used for dynamic range compression and expansion.
By companding the signal, this can reduce the noise
components.
The UTC
8507
includes compressor, expander,
pre-amp, filter amp, limiter and mute/bypath logic.
FEATURES
* Wide Supply Voltage (2.4 ~ 7V )
* Easy Gain Control
* Mute/Bypath Logic
* Data In/Out Pin
