Overview
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.
Features
• Silicon gate CMOS process for low switching noise
Functions
• Volume: 0 dB to –68 dB (in 2 dB steps) and –∞;
• Loudness: Taps are provided at the –20 dB positions in
• An address selection pin (the S pin) allows two
• Serial data input: Supports CCB* format communication

control function. A loudness function can be
implemented by attaching external RC circuits at these
tap points.
