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.

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.

■Features

・Built-in 7channel high sound quality operational amplifier.

・Wide volume range.

＋31.5dB〜－95.0dB, MUTE (0.5dB/step, 255 steps)

・Maximum input signal amplitude

4.2Vrms (±6V power supply)

・Low distortion (THD)

0.0004％ typ. (Input=1Vrms@1kHz, Gain=0dB）

・Low residual noise

1.2μVrms typ. (Gain=MUTE, IHF-A)

・Power supply voltage

±4.75V〜±6.6V

・Silicon gate CMOS process.

・48-pin plastic LQFP (YAC523-VZ)
