CMOS LSI
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.
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.
