I am now desinging circuits with AD5535 for MEMS application.
The MEMS device works well up to 190V and breaks over 200V.
I am afriad that the high voltage Vpp (225V) directly go through AD5535 to the MEMS device,
in case of powering on and/or temporary blackout of other low supply voltages.
Are there special sequences of powering on or some constraints of the suppy order?
And are there forbidden states of combination of on/off of supply voltages of
225V(Vpp), +5V(V+,AVcc), -5V(V-), 3.3V(DVcc), 4.096V(REF_IN)?
Thank you for in advance.
