■ 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 factor can be 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.
