8.3.3 Input Common-Mode Range

The linear input voltage range of the INA818 input circuitry extends within 1.5 V (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 58, Figure 53, and Figure 54. The common-mode range for

other operating conditions is best calculated using the Common-Mode Input Range Calculator for Instrumentation

Amplifiers.
