UTC 8507 LINEAR INTEGRATED CIRCUIT UTC UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R123-006,B COMPANDER

DESCRIPTION

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.
