YAC520 HGVC1 High Grade Volume Control s Outline YAC520(HGVC1) is a high grade stereophonic digital volume for high end audio system. It provides wide dynamic range and low distortion as well, and can control individual channels in 256 www.DataSheet4U.com steps with 0.5 dB per step. The use of 16 bit serial data interface allows daisy chain connection of several devices for multi channel system. Zero Crossing Detection function suppresses audible noise at quick change of the volume. YAC520 opera.

YAC520 HGVC1 High Grade Volume Control s Outline YAC520(HGVC1) is a high grade stereophonic digital volume for high end audio system. It provides wide dynamic range and low distortion as well, and can control individual channels in 256 www.DataSheet4U.com steps with 0.5 dB per step. The use of 16 bit serial data interface allows daisy chain connection of several devices for multi channel system. Zero Crossing Detection function suppresses audible noise at quick change of the volume. YAC520 operates on a single 5 volt power supply, and it is possible to input signal of up to 7.9Vrms by using three types of connection methods. Development evaluation board, DMB-HGVC1, equipped with PC interface is available. s Features q Wide volume range (can be used in three ways) q Adjustment step q Gain Error q Low distortion factor q Low residual noise A: +32.0 to – 95.0dB IN1=IN2 (Input < 2.0Vrms @VDD=5V) B: +29.5 to – 97.5dB IN2=GND (Input < 2.6Vrms @VDD=5V) C: +20.0 to – 107.0dB IN1=GND (Input < 7.9Vrms @VDD=5V) adjustable in 256 steps, with 0.5dB per step ± 0.1dB 0.001% (input=150 mVrms, gain=+16dB) 1 µVrms (gain=- ) s Others Process Package Power supply voltage Operating temperature Power consumption CMOS process 20 SSOP (YAC520-E) 5V 0 to +70 ºC 100 mW @VDD=5.0 V YAC520 CATALOG CATALOG No.: LSI-4AC520A4 2001.12 YAC520 s Block Diagram VREF + - LIN2 LIN1 www.DataSheet4U.com Vref Generator & Reset pulse Generator LOUT 256 VREF DVSS DVDD L Zero Cross Detection AVSS AVDD R Reset ICN TE Control Register ZCEN SDATAO 16 S/P Register SDATAI CSN SCLK 256 RIN1 RIN2 ROUT + VREF 2 YAC520 s Pin Assignment SCLK SDATAO 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 SDATAI CSN ZCEN ICN TE RIN1 RIN2 AVSS LIN2 LIN1 www.DataSheet4U.com DVDD DVSS AVSS AVDD ROUT VREF LOUT AVSS Top View 3 YAC520 s Pin Functions • Power supply pins AVDD – AVSS – DVDD – DVSS – Analog power supply (+5.0 V) Analog ground Digital power supply (+5.0 V) Digital ground • Analog Pins LIN1 – Left Channel Analog input 1 Lch analog input pin 1 Gain setting ranges from +32 dB to – 95 dB when the signal inputted to LIN2 is inputted this pin, and gain setting ranges from +20.0 dB to – 107.0 dB when it is grounded through a capacitor.
