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
