Serial Data Control Dual Electronic Volume
Description
The M62429 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 –83 dB (1 dB/step), –∞ (Independent control is allowed in each channel) Low noise and low distortion VNO = 5 µVrms (ATT = –∞, JIS-A) THD = 0.01 % Typ. (V0 = 0.5 Vrms, DIN-AUDIO)
Recommended Operating Conditions
Supply voltage range: VCC = 4.5 to 5.5 V
Rated supply voltage: VCC = 5 V
