I'm designing an op amp integrator with a 100nF capacitor, and need to include a logic level reset/discharge option. I would like to use the DG467 analog switch due to its low cost and small package, however I am concerned about the current rating and on resistance.
Worst-case: the capacitor has the full 10V supply voltage across its terminals (this would only happen in a fault condition), the reset switch is turned on. According to LTspice, the capacitor would discharge in ~10μs, assuming that the switch has a 10Ω on resistance. This will produce a 1A pulse, 10x the "absolute maximum rating" (100mA for 1ms pulsed with a 10% duty cycle).
My question: is a fast (i.e. less than 10μs) 1A pulse likely to destroy the switch? Is it necessary to add a 100Ω series resistance in order to keep the current less than 100mA, and thus increasing the discharge time to 100μs?
