Overview
The LV3319PM is an electronic volume and tone IC implements a rich set of audio control functions with a minimal
number of external components. Functions include input selection switching function, an input gain, volume, loudness,
balance, fader, general-purpose ports and bass/mid/treble control.
Features
 It is possible to eliminate from the external components of equalizer control block by SCF technology.
 Zero-cross switching circuits (Volume control block , Fader control block and General purpose volume block), soft
step (3 band equalizer control) and soft mute circuits used for low noise even when input signals are present.
 Low power consumption due to the use of BiCMOS process.
Functions
 Input switching :
Single-end inputs (3 input systems).
Single-end inputs (2 input systems) or differential input (1 input system).
Differential input (1 input system).
 Input gain control :
The input single can be amplified by 0 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 :
The bass control gain can be maximum boost +20dB position and maximum cut -20dB position.
( +20dB to -20dB in 1dB steps.)
The bass control center frequency 60Hz/70Hz/100Hz/120Hz can be selected.
The bass control quality factor 1.0/2.0 can be selected.
