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 factor can be obtained. www.DataSheet4U.com 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.
■Features
Built-in 2channel 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) 0.0002% 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. 24-pin plastic SSOP. The plating of pins is lead-free.(YAC526-EZ)
