The maximum voltage that can be applied to the input pins is 40V, but it's recommended to keep it below 30V to ensure accurate measurements.
The gain of the INA821 can be calculated using the formula: Gain = 5V / (Rgain x Vref), where Rgain is the gain resistor value and Vref is the reference voltage.
The REF pin is used to set the reference voltage for the internal ADC. It can be connected to a voltage source or left open-circuit to use the internal 2.048V reference voltage.
Yes, the INA821 can be used with a single-supply voltage, but the input common-mode voltage range will be limited. It's recommended to use a dual-supply voltage for optimal performance.
The INA821 outputs 16-bit data in a 2's complement format. The data can be read through the SPI interface and processed using a microcontroller or other digital signal processing unit.
