Product Summary

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 aimsfor improved listenability and an excellent cost-performance ratio. Applications of the LA4663 include: Radio/cassette players with built-in CD/MD players, microcomponent stereo systems, active speakers, electronic musical instruments, and other audio devices.

Parametrics

LA4663 absolute maximum ratings: (1) Maximum supply voltage VCC max: 24V; (2) Maximum output current Io peak, Per channel: 3.5A; (3) Allowable power dissipation Pd max: 37.5W (With an arbitrarily large heat sink) ; (4) Operating temperature Topr: -20 to +75°C; (5) Storage temperature Tstg: -40 to +150°C.

Features

LA4663 features: (1) Wide operating supply voltage range (V op): 5.5 to 22V (Certain conditions may apply.) ; (2) High ripple rejection ratio: 60 dB (typical) ; (3) Power: 16 W×2 (VCC=15V/6Ω) , 13 W×2 (V = 12 V/4Ω), 6.5 W×2 (V=9V/4Ω) ; (4) Built-in signal muting circuit (AC muting) reduces the number of external components and provides muting with minimal switching noise; (5) tartup 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.
