UTA31101扩展器IC

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.

* 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
