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 W 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.

Features
