I have an AD8065 configured as a TIA for an input current source.
The AD8065 is powered by +/- 5V.
The AD8065 V+ is connected through 5k to 0V.
The feedback from output to V- is through 2 100k resistors in series with a centre tap of 5k to 0V.
There is a small 100p for reducing the gain.
I suspect that on occasion, the input current source is shorting momentarily to one of the rails, either + or - 5V.
Obviously the AD8065 will give incorrect output during this time and over some recovery time.
My question, is this "overdrive" likely to cause damage to the AD8065?
My understanding is that the internal diodes should just drive the V- to approx. the voltage at V+ and thus the maximum of 1.8V differential (from datasheet) would be avoided.
Is this correct?
Thanks
David
