Learn types of rectifier circuit using op-amp. A diodes cannot rectifier ACV lower mV. But 741 rectifiers can help it, in filters, signal measurements, etc.
This is all simple LM741 circuits, it's so useful, LM741's general purpose single OP-AMP. UA741's high performance monolithic OP-AMP on single silicon chip.
I love to collect a lot of circuits. A filter circuit is important in Electronics. I will show you many ideas of noise hum, high-low frequency and more. Some you will…
The Simple long duration timer circuit using OP-AMP, If build the RC timer only that long time delay we need too many resistors and capacitors may be error [...]
