Overview
The LC75372E is an electronic volume control that can
implement volume, balance, fader, bass/treble, loudness,
input switching, and input level control functions with a
minimal number of external components.
Features
Volume: Provides 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 channels
independently.
Fader: This function can attenuate either the rear or the
front outputs over 16 positions. (From 0 to –20 dB in
2-dB steps, from –20 to –25 dB in one 5-dB step, from
–25 to –45 dB in 10-dB steps, –60 dB, and –
∞
.)
Bass/treble: Forms an NF-type tone control circuit (LUX
type) with the addition of external capacitors. The base
and treble controls each have 15 positions.
Loudness: The volume resistor ladders are tapped
starting at the –20-dB position. A loudness function can
be implemented by adding external RC circuits at these
taps.
The signal can be selected from one of three inputs for
each of the left and right channels. The input signals can
be amplified from 0 to +18 dB in 6-dB steps.
On-chip buffer amplifiers for a minimum of external
components.
Minimal switching noise due to fabrication in a silicon-
gate CMOS process.
Built-in reference voltage generation circuit
Serial data input: Supports CCB format communication
with the system controller.
