HA13118
18 W BTL Audio Power Amplifier
ADE-207-329 (Z)
1st Edition
Dec. 2000
Description
The HA13118 is power IC designed for component car stereo amplifiers. At 13.2 V to 4 Ω load, this power
IC provides an output power of 18W with 10% distortion.
It is easy to design as this IC employs internal each protection circuit and the new small package.
