7.3.1 Gain Options and Resistors

The gain value of the INA600 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 approximately ±15% while maintaining tighter gain error (tolerance) numbers as specified in the Electrical Characteristics table.

Table 7-1 Gain Selection
DEVICE VERSION INPUT RESISTOR FEEDBACK RESISTOR GAIN
INA600 A 1.2MΩ 240kΩ 1/5
B 1.2MΩ 120kΩ 1/10
C 1.2MΩ 100kΩ 1/12
D 1.2MΩ 66.66kΩ 1/18
E 1.2MΩ 50kΩ 1/24
F 1.2MΩ 33.33kΩ 1/36
