7.3.1 Gain Options and Resistors

The gain value of the INA500 is given by the ratio of feedback resistor and input resistor. The gain options are offered across different device variants as provided in Table 7-1. While the typical value of input and feedback resistors are shown in the following table, it is important to note that these values can vary together by about ±15% while maintaining tighter gain error (tolerance) numbers as specified in the Electrical Characteristics table.

Table 7-1 Gain Selection Table
DEVICE INPUT RESISTOR FEEDBACK RESISTOR GAIN
INA500A 1.08MΩ 1.08MΩ 1
INA500B 1.44MΩ 0.72MΩ 0.50
INA500C 1.68MΩ 0.42MΩ 0.25
