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 2.1-
channel audio systems to pre-amplify the signal from the main chip
audio.
FEATURES
