Ordering number : EN5914 CMOS IC LC75396NE Single-Chip Electronic Volume Control System Overview The LC75396NE is an electronic volume control system providing control over volume, balance, 5-band equalizer, and input switching based on serial inputs. Package Dimensions unit: mm 3159-QFP64E [LC75396NE] Functions • Volume control: The chip provides 81 levels of volume attenuation: in 1dB step between 0 dB and –79 dB and –∞. Independent control over left front/rear and right front/rear channels provides balance control. • Equalizer: The chip provides control in 2-dB steps over the range between +10 dB and –10 dB. Four of the five bands have peaking equalization; the remaining one, shelving equalization. • Selector: The left and right channels each offer a choice of five inputs.
