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
www.DataSfhaecteotr4cUa.ncobme obtained.
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.
