Overview
Ordering number : ENN5905A Monolithic Linear IC LA4663 Two-Channel 16-W BTL General-Purpose Audio Power Amplifier 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 costperformance ratio.
(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 Applications Radio/cassette players with built-in CD/MD players, microcomponent stereo systems, active speakers, electronic musical instruments, and other audio devices.

5 to 22 V (Certain conditions may apply.
) • High ripple rejection ratio: 60 dB (typical) • Power: 16 W × 2 (VCC = 15 V/6Ω), 13 W × 2 (VCC = 12 V/4Ω), 6.
5 W × 2 (VCC = 9 V/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.

7 seconds.
The LA4663 provides distortion-free startup, since output is only generated after the supply voltage reaches the midpoint at power on.
