8.1.1 Linear Operating Input Range

The linear operating input voltage range of the PGA854 input circuitry extends within 3V (maximum) of either power supply. This device maintains excellent common-mode rejection throughout this range at all temperatures. The linear operating input common-mode range is a function of the input common-mode voltage, input differential voltage, gain, and output common-mode voltage.

Figure 8-1 to Figure 8-4 show the valid common-mode range to enable valid output voltage at no load condition.
