DESCRIPTION
The UTC UTA31101 is a precision dual gain control circuit
designed for low voltage applications. The UTC UTA31101
channel 1 is an expandor, while channel 2 can be configured
either for expandor or compressor.
FEATURES
* Wide operating supply voltage range: V
CC
=1.8~9V
* For noise reduction, compressor and expandor are incorporated
into a package.
* Low operating supply voltage and small consumption current
make this IC suitable for its application to the sets using the
battery such as the codeless telephone set. etc.
