M62429P/FP
M62429P/FP
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 -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)
