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.)
