HA1388 18W BTL Audio power amplifier circuit diagram
HA1388 is an audio power amplifier IC. It uses 12-pin single in-line plastic package structure. The output power is 18W without output coupling capacitor when the supply voltage is 13.2V, 4Ω load impedance and 10% distortion. Thereis overvoltage and thermal shutdown protection in the circuit and fewer external components. The audio Power Amplifier is suitable for car radio. HA1388 Internal circuit diagram and typical application circuit are shown as below.
