1 UNISONIC TECHNOLOGIES CO., LTD UTA31101 Preliminary LINEAR INTEGRATED CIRCUIT 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: 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. V CC(MIN) =1.8V (T A =25 C I CCQ =2.7mA (Typ.) (V CC =3V, T A =25 C) * Recommendable operating supply voltage: V CC =3V ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing UTA31101L-D16-T UTA31101G-D16-T DIP-16 Tube - UTA31101G-S16-R SOP-16 Tape Reel - UTA31101G-P16-R TSSOP-16 Tape Reel MARKING DIP-16 SOP-16 / TSSOP-16 1 of 7 Copyright 2016 Unisonic Technologies Co., Ltd
