CMOS LSI
LC75366, 75366M
Two-Channel Electronic Volume Control
Overview
Package Dimensions
The LC75366 (DIP20) and the LC75366M (MFP20) are
electronic volume controls that can be controlled by serial
input data and provide volume, balance and loudness
functions.

3021B-DIP20
[LC75366]
Features
• Silicon gate CMOS process for low switching noise
Functions
• Volume: 0 dB to –68 dB (in 2 dB steps) and –∞;
36 positions.
A balance function can be implemented by controlling
the left and right channel volume settings independently.
• Loudness: Taps are provided at the –20 dB positions in
the 10 dB step resistor ladder used by the volume
control function. A loudness function can be
implemented by attaching external RC circuits at these
tap points.
• An address selection pin (the S pin) allows two
LC75366 chips to be used on the same bus.
• Serial data input: Supports CCB* format communication
with the system controller.
