LV3329PE

www.DataSheet.co.kr Ordering number : ENA1856 Bi-CMOS LSI LV3329PE Overview For Car Audio Systems Electronic Volume IC 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. Continued on next page. CCB is a registered trademark of SANYO Electric Co., Ltd.
