Absolute Maximum Ratings (Common-Mode Input Voltage)

Common-Mode Input Voltage

The absolute maximum rating for common-mode input voltage indicates the maximum voltage that can be applied without causing degradation of IC characteristics or damage [given that the same potential is supplied to both the +Input (non-inverting input) and -Input (inverting input) pins].
The absolute maximum rated common-mode input voltage, unlike the common input voltage range listed in the electrical characteristics, does not guarantee normal IC operation.
To ensure normal IC operation, the common-mode input voltage range must be followed.
In general, the absolute maximum common-mode voltage is VEE-0.3V and VCC+0.3V, but for products without a protection element at the VCC side, voltages up to the absolute maximum rated supply voltage (i.e. VEE+36V) can be supplied, regardless of supply voltage.
In this way, the common-mode input voltage is determined by the input pin protection circuit configuration, parasitic elements, input transistor withstand voltage, and other factors.
In addition, in the case where forward voltage is supplied to the ESD protection element (diode), VEE-0.3V and VCC+0.3V indicate the voltage range where the protection element does not operate.
