TI's OPAMPPRO,Lighning detection and an ADC

May 20, 2007 2 Replies

I am trying to make a lightning detection circuit. And have a nice detector front and it needs to be matched to an ADC on a Zilog Z8 encore mpu.



The front end is +/-15Volts. And the ADC is a 0-3v affair.



It works so good I am afraid to alter the detector main opamp. I was wondering if TI's OPAMPPRO computer design program would be useful in this endeavor.



I am a novice trying to learn the Z8 and its ADC. I tried a 0-5 volt opamp- LM325 as the interface and lost alot of sensitivity.



Any ideas.. Thanks in advance.



I am investigating the rise time characteristics of the static Em field for a lightning bolt. IT might have some directionality? Aleviating the need for orthoganal magnetic coils to detect bolt direction?



If found this site intriguing...

Thanks!

I got the TI OPAMPPRO to spit out a diagram of the interface circuit. It matchs 0-15 volt to a 0-3 volt output.
