SERIAL DATA CONTROL DUAL
ELECTRONIC VOLUME
DESCRIPTION
The UTC U2429 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 ~ -83dB (1dB/step), -∞
(Independent control is allowed in each channel)
* Low noise and low distortion
VNO = 5µVrms (ATT = -∞)
THD = 0.01% Typ. (V0 = 0.5Vrms)
