Hi,
Please excuse me to ask a question about an ADG419 applicayon under unusual operation condition.
I have to ask.
The part is operated from VDD=VL=+9V, VSS=GND=-9V, and S1, S2 ,D =-1V to 7V.
VIN is driven by +/-10V source with a 10kohm current limiting resistor between the sorce and
VIN terminal, thus the VIN voltage is clamped to VSS minus a diode drop and VDD plus a diode
drop ,respectively.
Q1: Is it correct to assume the part will be safe from the absolute maximum ratings point of view
beacuse the condition does not violtate the ratings?
Or could it be detroyed by a possible latch-up sooner or later?
Q2: Will the VIN LOGIC circuitry work normally under the inputs that excced the supply rails,
assuming the part will not be destroyed?
Best Regrads,
Lux
