I have been using an AD8092 with an AD835 four quadrant amplifier. The circuit has been used now in product for sometime with no problems but recently i have a latch up problem with the circuit.
The output of the AD835 is in the feedback of the AD8092 op-amp and I am comparing it with an input signal of some pules. The output of the op-amp is the square-root of the input signal. The output of the AD835 now latches high and doesn't follow the input signal of the op-amp.
I need some help.
It will be very cool if you attach a detailed circuit because it will eliminate the possibility of misunderstanding:)
Unfortunately, your schematic has very low resolution. Please, try to remake it in high quality.
Which the voltage range at AD835 inputs are? In my opinion, latching of AD835 may be caused by overload of inputs.

What is the output voltage in this case?
