LC75344M
Two-Channel Electronic Volume Control System
Overview
The LC75344M 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.
