We found a problem with the OPA4134.
When we use below circuit and test condition. we found the output goes to positive saturation with this configuration. Instead, when we use the competition part of MAX4423, the problem is gone. what happened?
FR73=FR74=NA
FR68=FR85=FR79=FR82=10K
E5V= 5V Supply
REF3.3V= Connected to GND
B+ = 1V
B- = GND
Thanks.
