Three-Channel Audio Amplifier

Three-Channel Audio Amplifier 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 By Silan
