Overview
The LC75392 (DIP-30SD) and the LC75392M (MFP-
30S) are electronic volume control ICs that provide input
and output switching, volume, and tone control functions
controlled by data transferred over a serial interface.
Functions
Input and output switching: Four inputs and outputs can
be switched independently.
Volume control: A balance function can be implemented
by controlling the left and right levels independently.
Each channel can be set to 0 to 20 dB in 2 dB steps,
20 to 32 dB in 3 dB steps, 32 to 52 dB in 4 dB
steps, 52 dB to 70 dB in 4.5 dB steps, and
.
Tone controls: Internal switches are provided to select
between four sets of frequency characteristics. A buffer
function can be implemented using external
components.
Features
Serial data interface: Support for control and
communication in the CCB format.
