CMOS IC
LC7538JM
Electronic Volume Control System
for Car Audio
Overview
The LC7538JM is a fully equipped electronic volume IC
which permits significant reductions in externally
connected components while providing ample volume,
balance, loudness, fader, bass and treble control functions.
• On-chip op amplifier for caching applications reduces
external components.
• Reduced switching noise with silicon gate CMOS
processor.
• All controls performed using serial data input (CCB).
Features
• Volume
: 81 positions ranging from 0 dB to -79
dB (in 1 dB increments) plus -.
Separate left and right control provides
excellent balance function.
• Loudness
: Loudness operation provided by
externally attached CR to activate tap
at the -20 dB position of the volume
ladder resistor.
• Fader
: Fader function traversing 16 positions
with rear or front attenuated output
only (these 16 positions consist of 2
dB step intervals ranging from 0 dB to
-20 dB, 5 dB step intervals ranging
from -20 dB to -45 dB, plus the end
settings of -60 dB and -).
• Bass and Treble: Using externally attached C
(capacitor), the LC7538JM provides
bass-treble mutual 15-position control
and formats a NF-form tone control
circuit (LUX form).
