HA13119
Dual 5.5 W Audio Power Amplifier
Description
The HA13119 is power IC designed for car radio and car stereo amplifiers. At 13.2 V to 4
load, this
power IC provides output power of 5.5 W with 10 % distortion.
It is easy to design as this IC employs internal each protection circuit and the new small package.
