LV3313PM
For Car Audio Systems
Electronic Volume IC
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.)
