FAQ

Does the AD8624ACPZ-RL exhibit phase reversal?

No, the device is designed to prevent output phase reversal even if one or both inputs exceed the specified input voltage range but remain within the supply rails.

What is the maximum differential input voltage?

The internal diodes and series resistors limit the maximum differential input voltage to ±10 V or the supply voltage, whichever is less.
