[LC75396NE]
Functions
鈥?Volume control:
The chip provides 81 levels of volume attenuation: in 1-
dB step between 0 dB and 鈥?9 dB and 鈥撯垶.
Independent control over left front/rear and right
front/rear channels provides balance control.
鈥?Equalizer:
The chip provides control in 2-dB steps over the range
between +10 dB and 鈥?0 dB. Four of the five bands
have peaking equalization; the remaining one, shelving
equalization.
鈥?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.
鈥?Serial data input
鈥?Supports CCB* format communication with the
system controller.
