LV3313PM

Overview

The LV3313PM is an electronic volume IC that implements a rich set of audio control functions including input

selection switching function, an input gain, volume, loudness, balance, fader, and bass/treble control.

Features

 Zero-cross switching circuits (Input gain control block and Volume control block) can switch signal detection

location automatically.

 Zero-cross switching circuits (Input gain control block and Volume control block) and soft mute circuits used for low

noise even when input signals are present.

 Low power consumption due to the use of BiMOS process.

 All functions are controlled using serial data (CCB).

Functions

 Input selector :

Four input signals can be selected (three single-ended inputs and one differential input).

 Input gain control :

The input signal can be amplified by 0dB to +18dB (1dB steps).

 Loudness control :

Taps are output starting at the -32dB position of the ladder resistor and a loudness function implemented with

external capacitor and resistor components.

 Volume control : +10dB to -79dB/- (1dB steps)

L/R independent control.

 Bass control : +12dB to -12dB in 2dB steps

 Treble control : +12dB to -12dB in 2dB steps

 Fader control :

The fader volume can be attenuations by one of 16 levels. Independent control each four channels. (A total of 16

settings with attenuations of 0dB to -2dB in 1dB steps, -2dB to -20dB in 2dB steps, and -30dB, -45dB, - 60dB and

-

dB settings.)
