Question
My query is with how the device reacts on power up.
When the power to the device is ramping up below 1.7V, how does the output
respond?
I have used the ADCMP341 (non-inverting output) and the output tracks the power
rail and then for our set-up once a sufficient power level is reached, the
device switches low (the correct logic state).
How does the ADCMP343 (inverting) react during this 0 to 1.7V power up?
Answer
The application engineer has checked this on the bench here, and we can confirm
that the ADCMP343 output will be Hi-Z as the power supply rises up until it
starts to operate, at which point the output will depend on the state of the
inputs.
