Hi
I have the following circuit converting current from a psd to Voltage for input into an ADC.
I do not have LT1491's any more and want to use an LM324 as I have plenty of these in stock. Can people guide me with the redesign. For me the major block seems to be the +-5 V input of the LT1491. How would I go about implementing that into an LM324....
Secondly. the signal in has to be from a distance of 65 inches. My question is would it be better to run the cable before ICIA or have the connection cable running between IC1A and IC1B.
