UNISONIC TECHNOLOGIES CO., LTD UTC571N LINEAR INTEGRATED CIRCUIT COMPANDER DESCRIPTION The UTC571N is a versatile low cost dual gain control circuit in which either channel may be used as a dynamic range compressor or expandor. Each channel has a full-wave rectifier to detect the average value of the signal, a linerarized temperature-compensated variable gain cell and an operational amplifier. The UTC571N is well suited for use in cellular radio and radio communication systems, modems, telephone, and satellite broadcast/receive audio systems. FEATURES * Complete compressor and expandor in one Chip * Temperature compensated * Greater than 110dB dynamic range * Operates down to 6VDC * System levels adjustable with external components * Distortion may be trimmed out * Dynamic noise reduction systems * Voltage-controlled amplifier ORDERING INFORMATION Ordering Number Lead Free Halogen Free UTC571NL-S16-R UTC571NG-S16-R UTC571NL-S16-T UTC571NG-S16-T UTC571NL-S16W-R UTC571NG-S16W-R UTC571NL-S16W-T UTC571NG-S16W-T www.unisonic.com.tw Copyright © 2012 Unisonic Technologies Co., Ltd Package Packing SOP-16 SOP-16 SOP-16(W) SOP-16(W) Tape Reel Tube Tape Reel Tube 1 of 4 QW-R121-021.B UTC571N PIN CONNECTIONS BLOCK DIAGRAM UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw LINEAR INTEGRATED CIRCUIT 2 of 4 QW-R121-021.B UTC571N LINEAR INTEGRATED CIRCUIT ABSOLUTE MAXIMUM RATINGS(TA=25 °C, unless otherwise specified) PARAMETER SYMBOL VCC RATINGS UNITS 18 V SOP-16 400 Power Dissipation PD mW SOP-16(W) 625 Junction Temperature TJ +150 °С Operating Temperature TOPR -20 ~ +85 °C Note: Absolute maximum ratings are those values beyond which the device could be permanently damaged.
