Electronic Volume IC
Overview
The LV3329PE is an electronic volume and tone IC that implements a rich set of audio control functions with a
minimal number of external components. Functions include input selection switching, an input gain, volume, loudness,
balance, fader, bass/mid/treble control, and fixed equalizer.
Features
• It is possible to eliminate from the external components of equalizer control block by SCF technology.
• Zero-cross switching circuits, soft steps (bass block and mid 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 controls performed using serial data input (CCB).
Functions
• Input selector :
Four of the input systems are single-end inputs, one uses differential inputs.
• Input gain control :
The input gain can be amplified by 0 to +19dB (0 to 5dB/1.25dB steps, 5 to 11dB/1.5dB steps, 11 to 19dB/2dB 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 : 0dB to -79dB/-∞ (1dB steps)
L/R independent control.
