JAJSPU3 May 2024 INA791B
ADVANCE INFORMATION
Figure 6-8 shows adjustable gain set to unity gain or 1. In this configuration OUT is connected to FB without any external resistor. This unity gain sets INA791x to default minimum gain of 20mV/A. Equation 3 can be used to calculate the total gain of the system. The REF pin is connected to external reference based on needed output voltage setting as described in Adjusting the Output With the Reference Pin.
