SD7401

SD7401 SIX-CHANNEL AUDIO AMPLIFIER DESCRIPTION SD7401 is a 6-channel audio amplifier with built-in microphone input amplifier. High quality audio output is available through simple peripheral circuit and the amplifier gain can be adjusted flexibly by external resistor. It is widely used as pre-amplification in various multi-channel audio systems. FEATURES * BICMOS technology * Dual power supply (+5V/-12V) * Built-in voltage regulation module * Low distortion * Standby function * Mute function * ON/OFF POP noise suppression SSOP-20-225-0.65 APPLICATIONS * Audio amplification system, such as VCD/DVD ORDERING INFORMATION Part No. SD7401 Package SSOP-20-225-0.65 Marking SD7401 BLOCK DIAGRAM www.DataSheet4U.com HANGZHOU SILAN MICROELECTRONICS CO.,LTD Http://www.silan.com.cn REV:1.0 2008.07.07 Page 1 of 7 SD7401 ABSOLUTE MAXIMUM RATINGS (Unless otherwise specified, Tamb = 25°C) Characteristics Supply Voltage (VCC-Vss) Operating Temperature Storage Temperature supply.
