Technology
ACE624
Serial data control dual electronic volume
Description
The ACE624 is a dual channel electronic volume controlled with 2-wire serial data. The built-in reference
circuit can compose of an electronic volume with less external parts.
Features
• Built-in reference circuit
• Control with serial data Volume 0 to -83dB (1dB/step), -∞ (Independent control is allowed in each
channel)
• Low noise and low distortion VNO=5μVrms (ATT=-∞, JIS-A) THD=0.01% Typ. (V0=0.5Vrms,
DIN-AUDIO)
