7.3.1.4 Wide Fixed Gain Output

The INA296x maximum gain error is ±0.01% at room temperature, with a maximum drift of ±1 ppm/°C over the full temperature range of –40°C to 125°C. The INA296x is available in multiple gain options of 10V/V, 20V/V, 50V/V, 100V/V, and 200V/V, which the system designer must select based on the desired signal-to-noise ratio and other system requirements, such as the dynamic current range and full-scale output voltage target.
