LC75348集成电路（IC）的音频专用规格书PDF中文资料

Overview

The LC75348 and LC75348M are electronic volume and tone control ICs that provide volume, balance, 2-band equalizer, input gain control, and input switching functions while requiring a minimal number of external components.

特性 Features

• Built-in buffer amplifiers reduce the number of external components required.

• Fabricated in a silicon gate CMOS process for minimal switching noise from built-in switches and minimal switching noise even when there is no input signal.

• Built-in zero cross circuits minimize switching noise when input signals are present.

• Built-in VDD/2 reference voltage generator circuit.

• All functions are controlled from serial data. Supports the CCB bus.
