LV3311PNM
Bi-CMOS LSI
For Car Audio Systems
Electronic Volume IC
Overview
The LV3311PNM is an electronic volume 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,
bass/mid/treble and subwoofer 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 and Fader control block), soft step (3 band equalizer control and
Suboofer 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.
• All functions are controlled using serial data (CCB).
Features
• Input selector :
Four of the input systems are single-end inputs, one uses differential inputs.
• 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.
