LA4663N
Overview
The LA4663N 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 LA4663N aims for improved listen
ability and an excellent cost-performance ratio.
Applications Radio/cassette players with built-in CD/MD players, micro-component stereo systems, active speakers,
electronic musical instruments, and other audio devices.
Functions
Wide operating supply voltage range (VCC op): 5.5 to 22V (Certain conditions may apply.)
High ripple rejection ratio:60dB (typical)
Power: 16W×2 (VCC = 15V/6Ω), 13W×2 (VCC = 12V/4Ω), 6.5W×2 (VCC = 9V/4Ω)
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 LA4663N 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
