Overview
YAC523 EVR2 Electric Variable Resistance 2 ■Outline YAC523 (EVR2) is a 7ch high grade digital volume LSI for high-end audio systems.
Owing to its built-in high-quality sound operational amplifier, output with wide dynamic range and low distortion factor can be obtained.

DataSheet4U.
com YAC523 is able to control each channel through a serial data interface in 255 steps at 0.
5dB per step, and can allow configuration of a system with 8 channels or more by using a daisy chain connection.
Owing to its zero-cross detection function, the device is able to suppress audible noise that may occur at a quick volume change.
