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.
Package Dimensions
unit: mm
3086B-MFP10S
[LC75344M]
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.
