Overview
The LC75386NE-R and 75386NW are electronic volume
and tone control ICs that can implement volume, balance,
fader, bass/treble, loudness, input switching, and input
gain control functions with a minimum number of external
components.
Features
Volume: 81 positions: from 0 dB to –79 dB in 1-dB steps
and –
∞.
A balance function can be implemented by
controlling the left and right volume settings
independently.
Fader: Either the rear or front outputs can be attenuated
over 16 positions. (16 positions: From 0 dB to
–2 dB in 1-dB steps, from –2 dB to –20 dB in
2-dB steps, from –20 to –30 dB in one 10-dB step,
–45 dB, –60 dB, and –
∞.)
Bass/treble: Control over ±12 dB in 2-dB steps in each
band.
Input gain: The input signal can be amplified by from 0
dB to +18.75 dB in 1.25-dB steps.
Input switching: The left and right channels can each be
selected from one of 6 inputs. (Five are
single-ended inputs and one is a
differential input.)
Loudness: Taps are output from a 2-dB step volume
control ladder resistor starting at the –32-dB
position. A loudness function can be
implemented by attaching external capacitors
and resistors.
On-chip buffer amplifiers minimize the number of
required external components.
Minimal switching noise when no input signals are
present due to fabrication in a silicon gate CMOS
process that minimizes the noise generated by internal
switches.
Use of zero-cross switching circuits for internal switches
minimizes switching noise when signals are present.
Built-in VDD/2 reference voltage generator circuit
All controls can be set from serial input data.
