7.3.3 Input Common-Mode Range

The linear input voltage range of the INA828 input circuitry extends within 2 Volts 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 55, Figure 50, and Figure 51. The common-mode range for

other operating conditions is best calculated using the INA common-mode range calculating tool. The INA828

device can operate over a wide range of power supplies and VREF configurations, thus providing a

comprehensive guide to common-mode range limits for all possible conditions is impractical.
