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
