LC75344MD
CMOS LSI
Two-Channel Electronic
Volume Control System
http://onsemi.com
Overview
The LC75344MD is a two-channel electronic volume control IC that is controlled by data input over a serial interface.
Functions
Volume control: 0 dB to –50 dB in 1 dB steps, –52 dB to –78 dB in 2 dB steps, and –, for a total of 66 positions.
A balance function can be implemented by controlling the left and right channels independently.
Features
Built-in buffer amplifiers minimize the number of external components required.
Fabricated in a silicon gate CMOS process to minimize the switching noise generated by internal switches.
Built-in reference voltage generation circuit for the analog ground level.
All settings are controlled by data input over a serial interface that conforms to the CCB specifications.

Usage Notes
The states of the internal analog switches are undefined after power is first applied. Muting must be applied
externally until the control data has been sent.
When performing the initial settings after power is first applied, both the left and right channel initial settings
data must be sent before releasing the external mute.
Either cover the CL, DI, and CE lines with the ground pattern or use shielded lines to prevent high-frequency
digital noise from entering the analog signal system from these lines.
