Hello there chaps and chapettes,
I have been asked to fill the gap between a 5microamp signal pulsing at 10238 Hz and a 5V PIC ADC Pin. The pulse is being generated by and LED and picked up by a photodiode which in turn is providing me with the above signal. I must also filter any signals that might come through from the photodiode picking up natural light.
The parts should be available to buy and I'm able to use anything up to 12V to power the circuit
The use of OPamps would be preferable, as I sort of understand them, but I am struggling.
So far I have an unspecified OPamp doing a current to voltage conversion with an unspecified resistor over it, and that's it...I'm very bad with electronics and have had this sprung on me :S
Any help would be awesome!
Cheers!
