COMPANDER IC FOR CORDLESS TELEPHONE
DESCRIPTION
The UTC UTA31101 is a precision dual gain control circuit
designed for low voltage applications. The UTC UTA31101’s
channel 1 is an expandor, while channel 2 can be configured
either for expandor, or compressor.
FEATURES
* Wide operating supply voltage range: VCC=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.
VCC(MIN)=1.8V (TA=25°C
ICCQ=2.7mA (Typ.) (VCC=3V, TA=25°C)
* Recommendable operating supply voltage: VCC=3V |
