Overview
The LC75386NE is an electronic volume and tone control
IC that can implement a wide range of functions including
volume, balance, fader, bass and treble controls, loudness,
input switching, and input gain control with a minimal
number of external components.
Functions
Volume:
0 to –79 dB ( in 1-dB steps) and –
∞ for
a total of 81 settings.
A balance function can be implemented
by controlling the left and right channel
volume settings independently.
Fader:
The rear or the front outputs can be
attenuated over 16 settings.
(0 to –2 dB in 1-dB steps, –2 to –20 dB
in 2 dB steps, –20 to –30 dB in 10-dB
steps, –45 dB, -60 dB, and –
∞ for a
total of 16 settings.)
Bass and treble: Control over a ±12-dB range in 2-dB
steps in each band.
Input gain:
The input signal can be amplified from
0 to +18.75 dB (in 1.25-dB steps).
Input switching: One of 6 inputs can be selected for
each of the left and right channels.
(Five are single-ended inputs, and one
is a differential input.)
Loudness:
Taps are output from the –32-dB
positions of the 2-dB step volume
ladder resistors, and loudness operation
can be implemented by attaching
external capacitors.
Features
On-chip buffer amplifiers minimize the number of
external components required.
The low level of switching noise generated from internal
switches due to fabrication in a CMOS process
minimizes switching noise when no input signals are
present.
The use of built-in zero-cross switching circuits
minimizes switching noise when input signals are
present.
Built-in VDD/2 reference voltage generation circuit
All controls are controlled from CCB serial data input.
