Two-Channel 16-W BTL General-Purpose
Audio Power Amplifier
LA4663
Overview
The LA4663 is a BTL 2-channel power amplifier IC that
was developed for ease of use in general audio
applications. In addition to providing improvements in a
wide range of electrical characteristics, the LA4663 aims
for improved listenability and an excellent cost-
performance ratio.
Applications
Radio/cassette players with built-in CD/MD players,
microcomponent stereo systems, active speakers,
electronic musical instruments, and other audio devices.
Features
Wide operating supply voltage range (VCCop): 5.5 to
22 V (Certain conditions may apply.)
High ripple rejection ratio: 60 dB (typical)
Power: 16 W
× 2 (V
CC = 15 V/6),
13 W
× 2 (V
CC = 12 V/4), 6.5 W × 2 (VCC = 9 V/4)
Built-in signal muting circuit (AC muting) reduces the
number of external components and provides muting
with minimal switching noise.
Startup circuit with a start time of 0.6 to 0.7 seconds.
The LA4663 provides distortion-free startup, since
output is only generated after the supply voltage reaches
the midpoint at power on.
(The startup time can be modified in end products by
using this circuit in conjunction with the muting circuit
described above.)
Full complement of built-in protection circuits
(protection from shorting to ground, shorting to VCC,
load shorting, and overheating)
High audio quality, minimal impulse noise
