The TDA1010A is a monolithic integrated class-B audio
amplifier circuit in a 9-lead single in-line (SIL) plastic package. The device is primarily developed as a 6 W car radio amplifier for use with 4Wand 2 Wload impedances.
The wide
supply voltage range and the flexibility of the IC make it an attractive proposition for record players and tape recorders with output powers up to 10 W.

Circuit Amplifier TDA1010
This audio
amplifier Circuit is a class-B audio power amplifier using a TDA1010. It is easy to construct and has only a few external components. The circuit is designed with short circuit and thermal protection. It can drive loads as low as 1.6 ohm and is capable of deliveringover 10 watts from a 16 V DC power supply.
Assume VP = 14,4 V; RL = 2 W; Tamb = 60 °C maximum; thermal shut-down starts at Tj = 150 °C. The maximum sine-wave dissipation in a 2 W load is about 5,2 W. The maximum dissipation for music drive will be about 75% of the worst-case sine-wave dissipation, so this will be 3,9 W. Consequently, the total resistance from junction to ambient
