UTA31101

COMPANDER IC FOR CORDLESS TELEPHONE

 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

UTA31101 是一款台湾UTC的压缩扩展器IC，最初设计是无绳电话用的。这款IC我们常备现货。SOP-16封装，2500个一盘。                                          说明:UTC UTA31101是一种精密的双增益控制电路专为低压应用而设计。通道1是扩展器，而通道2可以配置用于扩展器或压缩器。                                           特征：*工作电源电压范围宽:VCC=1.8~9V 　*为了降低噪音，扩展器和压缩器结合在一起封装。　*工作电源电压低，消耗电流小，使该IC适用于使用电池，如无码电话机等。 VCC（最小）=1.8V（TA=25°C ICCQ=2.7mA（典型）（VCC=3V，TA=25°C）  *推荐工作电源电压:VCC=3V
