UTA31101

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: 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
