UTC UNISONIC TECHNOLOGIES CO., LTD. 1 QW-R502-031,A 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) DIP-8 SOP-8 PIN CONFIGURATION VCC VOUT2 VIN2 CLOCKDATA GND VOUT1 VIN1 PIN DESCRIPTION PIN No. PIN NAME FUNCTION

1 VIN 1 1-ch input pin

2 VOUT1 1-ch output pin

3 GND Ground pin

4 DATA Control data input pin. Inputs data in synchronization with clock. 5 CLOCK Clock input pin for transferring serial data. 6 VCC Power supply pin. Stabilize the pin with decoupling capacitor.

7 VOUT2 2-ch output pin

8 VIN2 1-ch input pin
