| 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 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 HA13119 Absolute Maximum Ratings (Ta = 25C) Item Operating supply voltage DC supply voltage Peak supply voltage Output current Power dissipation Thermal resistance Junction temperature Operating temperature Storage temperature Notes: 1. 2. 3. 4.
