I was wondering how long it takes the ad8235 chip to turn on from no power, and from shut-down mode.
I have just tested 3 units of AD8235 and the "wake-up" time after shutdown is measured to be at ~400uS.
Please be informed that the 90uS was performed with the following conditions:
+Vs = 5V, -Vs = GND
+IN = -IN = Vref = 2.5V
The Vo was at 2.5V level within around ~90uS as the +Vs is already enough to…
The specific parameter you wanted to know is not present on the datasheet.
I will try to look for other data pertaining to the "wake-up" time.
I will get back to you.
The information was very helpful. I was also noticed that AD8236 didn't have a shutdown pin. If I cut off power to the +Vs pin and start it up, would the AD8235/6 chips startup in 400uS as well?
Had an experiment for the AD8235 as well for the power-up, that is +Vs from 0V.
The measured power-up time is ~90uS.
