YAC526
EVR3
Electric Variable Resistance 3
■Outline
YAC526 (EVR3) is a 2ch 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.
YAC526 is able to control each channel through a serial data interface in 255 steps at 0.5dB per step, and
daisy chain connection can constitute a multichannel system.
Owing to its zero-cross detection function, the device is able to suppress audible noise that may occur at a quick
volume change.
