Electronic Volume Control System for
Audio Equipment
LC7537, 7537AN, 7537NE
Overview
The LC7537N is an electronic control LSI capable of
electronically controlling the volume, balance, loudness,
fader, bass, and treble functions individually with fewer
externally connected component parts.
Features
Enables controlling the below-listed functions with 3-
line serial data, including CE, DI, and CLK. Also, due
to 0 V to 5 V swing of the serial data input voltage,
permits the use of a general purpose microcomputer.
Volume :
Separately controls the Lch and Rch
volume levels across 81 positions over
the 0 dB to –79 dB (in 1 dB steps) range
and –
∞
, and consequently also serves
balance control purposes.
Loudness :
By virtue of a center tap provided at the
–20 dB position of the volume
controlling ladder resistors, permits
loudness to be controlled with
externally connected CR components.
Fader :
By varying only the rear or front output
level across 16 positions, provides fader
functions (in 2 dB steps over the 0 dB to
–20 dB range, and 5 dB steps over the
–20 dB to –45 dB range, and at –
∞
, for
a total of 16 positions).
Bass/Treble : With CR components externally
connected, forms an NF type tone
control circuit (Baxandall type) to
exercise control across 15 positions
over both the bass and treble functions
in 2 dB steps.
By virtue of its CMOS structure, the LSI operates under
a broad power supply voltage range from +4.5 V to +15
V, permitting the use of either a single or a dual ± power
supply, whichever is preferred.
