SC9260 Overview

Volume/sound effect control circuit

Features

SC9260 and SC9260S are I2C interface electronic volume control circuits designed for audio equipment using CMOS technology.


Two-channel electronic volume control circuit controlled by serial port (with equal loudness control)

Parameters

The attenuation can be controlled in the range of 0dB to -78dB, with 2dB/step.


Built-in loudness circuit (20dB tap)


Volume, balance and loudness circuits controlled via I2C serial data


Chip select input allows more than 2 chips to be controlled by the same bus


The use of high-precision polysilicon resistors ensures low distortion and high performance of the volume system.


Package: DIP-16-300-2.54, SOP-16-300-1.27(S)

Application

CD players, VCD players, DVD players, portable digital devices
