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…
