LV3313PM

www.DataSheet.co.kr Ordering number : ENA1257 Bi-CMOS LSI LV3313PM Overview Features For Car Audio Systems Electronic Volume IC 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. 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). 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 i...
