LC75366中文资料三洋数据手册PDF规格书

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.

特性 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.
