LC75396NE

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. The L5 and R5 inputs can be turned on and off independently. An external constant determines the amplification for the input signal. Serial data input — Supports CCB* format communication with the system controller. SANYO: QFP64E Features Built-in buffer amplifiers reduce the number of external parts required. Silicon gate CMOS process reduces the noise of built-in switch. VDD/2 reference voltage generation circuit built in. CCB is a trademark of SANYO ELECTRIC CO., LTD. CCB is SANYO’s original bus format and all the bus addresses are controlled by SANYO.
