HIT HA13119 Datasheet

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 Ω 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
 Surge protection circuit (more than 50 V)
 Thermal shut-down circuit
 Ground fault protection circuit
 Power supply fault protection circuit

• Low external components count
