Overview
THREE-CHANNEL AUDIO AMPLIFIER DESCRIPTION SD7402 is a 3-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.
Its audio output signal-noise ratio is 85dB, total harmonic distortion is 0.
05% and the channel separation is 78dB.
Based on BICMOS technology, SD7402 can stably work in +5V/12V system with built-in voltage regulator.
The built-in filter can improve the audio quality by attenuating the other signals.
The mute and ON/OFF POP suppression functions can suppress the POP noise in the input signal.
It is widely used as pre-amplification in various stereo and 2.
1channel audio systems to pre-amplify the signal from the main chip audio.
SOP-16-225-1.
27 APPLICATIONS FEATURES * BICMOS technology * Dual power supply (+5V/-12V) * Built-in voltage regulator * Low distortion * Standby function * Mute function and ON/OFF POP noise suppressi...
