HA13118
18 W BTL Audio Power Amplifier
ADE-207-329 (Z)
1st Edition
Dec. 2000
Description
The HA13118 is power IC designed for component car stereo amplifiers. At 13.2 V to 4
load, this power
IC provides an output power of 18W with 10% distortion.
It is easy to design as this IC employs internal each protection circuit and the new small package.
Features
Small outline package, easy to mount
Internal each protection circuits
Surge protection circuit
Thermal shut-down circuit
Ground fault protection circuit
Power supply fault protection circuit
