8.3.3 Input Common-Mode Range

The linear input voltage range of the INA821 input circuitry extends within 2 V of 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 54, Figure 49 and Figure 50. The common-mode range for other

operating conditions is best calculated using the INA common-mode range calculating tool. The INA821 device

common-mode range limits for all possible conditions.
