9.1.4.3 Low VSENSE Case 1: VSENSE < 20 mV, –16 V ≤ VCM < 0 V; and
Low VSENSE Case 3: VSENSE < 20 mV, VS < VCM ≤ 80 V

Although not designed for accurate operation in either of these regions, the INA20x-Q1 family of devices may have exposure to these conditions in some applications. For example, when monitoring power supplies being switched on and off with VS still applied to the INA20x-Q1, it is important to know what the device behavior is in these regions.

As VSENSE approaches 0 mV, in these VCM regions, the device output accuracy degrades. A larger-than-normal offset can appear at the current shunt monitor output with a typical maximum value of VOUT = 300 mV for VSENSE = 0 mV. As VSENSE approaches 20 mV, VOUT returns to the expected output value with accuracy, as specified in the Electrical Characteristics: Current-Shunt Monitor. Figure 9-3 illustrates this effect using the INA202-Q1 (gain = 100).
