7.3.1 Gain Options and Resistors

The gain value of the INA510-Q1 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 values of the input and feedback resistors are shown in the following table and the resistors are ratiometrically matched, note that the absolute resistor value can vary by approximately ±15% while still maintaining the tighter gain error (tolerance) numbers specified in the Electrical Characteristics table.
