8.3.3 Input Common-Mode Range

The linear input voltage range of the INA819 input circuitry extends within 1.5 volts (typical) of both power supplies and maintains excellent common-mode rejection throughout this range. The common-mode range for the most common operating conditions are shown in Figure 8-4 toFigure 8-7. The common-mode range for other operating conditions is best calculated using the Analog Engineers Calculator.
