Hi Ti colleague,
We are long customer to use LOG112. Now we want to fulfill redundancy LOG112 output circuits for one sensor, as attachment drawing. One sensor's current is split into two / redundancy LOG112.
Now we found that the two LOG112 will output differently too much, for example one output 2.1V while another output 0.5V, so can not realize redundancy. We find that in several samples if we increase the input resistance R7/R29 value to 1K Ohm or 750 Ohm (keep R7 = R29), then two channels output almost same voltage that different small than 0.03V and acceptable.
But is there some bad effect that input resistance brings? For example stable, frequency response ....
Thank you very much in advanced!
