LC75344M Datasheet (Sanyo Semicon Device) - Two-Channel Electronic Volume Control

LC75344M, Two-Channel Electronic Volume Control

Ordering number : ENN7332 CMOS LSI 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.
