SSGSC34119 Datasheet | SeCoS Halbleitertechnologie GmbH

DESCRIPTION The SGSC34119 is a low power audio amplifier integrated circuit intended (primarily) for telephone applications, such as in speakerphones. It provides differential speaker outputs to maximize output swing at low supply voltages (2.0V minimum). Coupling capacitors to the speaker are not required. Open loop gain is 80 d B, and the closed loop gain is set with two external resistors. A Chip Disable pin permits powering down and/or muting the input signal. FEATURES z z z z z z z z z Wide Operating Supply Voltage Range (2.0V to 16V), allows Telephone Line Powered Applications Low Quiescent Supply Current (2.7m A Typ) for Battery Powered Applications Chip Disable Input to Power Down the IC Low Power-Down Quiescent Current (65µA Typ) Drives a Wide Range of Speaker Loads (8.0Ω and Up) Output Power Exceeds 250 m W with 32Ω Speaker Low Total Harmonic Distortion (0.5% Typ) Gain Adjustable from <0 d B to >46 d B for Voice Band Requires Few External ponents PACKAGE DIMENSIONS REF.
