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
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.
