Opto-isolator (SFH628)

Opto-isolator (SFH628)

Definitely had it working with smooth output using 100nF & 100kΩ and with 10µF & 10kΩ but those are not equivalent RC values so also try 1kΩ if needed for other reasons, eg below Also now need to try with Vout feeding a microcontroller. Which will need its input pin pulling low (so 10kΩ might …
