I have a couple of 'bad' op-amps.
It is one 5 pin TO-220 power opamp. With max 3.5 Ampere output.
Same size and pins as for example LM1875/LM3875.
When I tried it for Audio output, it was a terrible crossover distortion
What possibly can I use it for.
Some sort of DC output power supply?
Voltage Regulated output maybe, using some Voltage reference at input?
Any ideas are welcome
Datasheet can no longer be found, but spec sheet say the following:
