Hi !
I have a problem with the linear tecnologies's IC LTC6915.
We used it for amplifier the output signal of a Wheatstone bridge , and this output can be negative.
For this reason we used a voltage regulator of 1,25 V connected with the Ref. Pin.
But if I put a negative value minor of 1.25 V the IC doesn't work .
Have you some Idea about this behavior ?
