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

·Low distortion THD = 0.1% typ

(Po = 0.5 W, f = 100 Hz to 10 kHz) THD = 1% typ

(Po = 3 W, f = 70 Hz to 40 kHz)

·Internal each protection circuits

¾Surge protection circuit (more than 50 V)

¾Thermal shut-down circuit

¾Ground fault protection circuit

¾Power supply fault protection circuit

·Low external components count
