LC75411WS集成电路（IC）的音频专用规格书PDF中文资料

Overview

The LC75411ES and 75411WS are electronic volume controllers that enable control of volume, balance, fader, bass/treble, loudness, input switching, and input gain using only a small number of external components.

特性 Features

• On-chip buffer amplifier cuts down number of external components

• Low switching noise generated by on-chip switch through use of silicon gate CMOS process, for low switching noise when there is no signal

• Low switching noise when there is a signal due to use of on-chip zero-cross switching circuit

• On-chip 1/2 VDD reference voltage circuit

• Controls performed with serial input (CCB)
