... THEORY OF OPERATION The AD8601/AD8602/AD8604 family of amplifiers are rail-to-rail input and output, precision CMOS amplifiers that operate from 2 5 the power supply voltage. These amplifiers use Analog Devices, Inc., DigiTrim® technology to achieve a higher degree of precision than available from most CMOS amplifiers. ...

... AD8601/AD8602/AD8604 INPUT OVERVOLTAGE PROTECTION As with any semiconductor device condition could exist that could cause the input voltage to exceed the power supply, the device’s input overvoltage characteristic must be considered. Excess input voltage energizes the internal PN junctions in the AD860x, allowing current to flow from the input to the supplies. ...
