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.
Functions
• Volume control:
The chip provides 81 levels of volume attenuation: in 1-
dB 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.
