LC75392, 75392M
Single-Chip Electronic Volume Control System
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.

[LC75392]
Functions
鈥?Input and output switching: Four inputs and outputs can
be switched independently.
鈥?Volume control: A balance function can be implemented
by controlling the left and right levels independently.
Each channel can be set to 0 to 鈥?0 dB in 2 dB steps,
鈥?0 to 鈥?2 dB in 3 dB steps, 鈥?2 to 鈥?2 dB in 4 dB
steps, 鈥?2 dB to 鈥?0 dB in 4.5 dB steps, and 鈥撯垶.
鈥one controls: Internal switches are provided to select
between four sets of frequency characteristics. A buffer
function can be implemented using external
components.
