8W audio power amplifier circuit composed of LM2002/LM2002A

LM2002/2002A is an audio power amplifier integrated circuit, which adopts 5-pin single in-line plastic package. These two integrated circuits have the characteristics of high output power, low distortion, low noise, few external components, high input impedance, and low startup impact noise. LM2002 has current limiting and thermal cut-off protection circuits; LM2002A has high voltage protection, and its maximum instantaneous power supply voltage can reach 40V. They are suitable for audio power amplifiers in car audio systems and ordinary portable and desktop recorders. The figure shows its BTU circuit.
