INA821IDGKR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the input pins is ±40V, but it's recommended to keep it within ±20V for optimal performance.
  • To ensure accurate current measurement, make sure to use a sense resistor with a low temperature coefficient, keep the sense resistor close to the INA821, and use a low-noise power supply.
  • The REF pin is used to set the reference voltage for the internal amplifier. Connect a voltage source (e.g., 2.5V) to the REF pin to set the reference voltage, or leave it open for a default 2.048V reference voltage.
  • The gain of the INA821 is calculated as (Rgain / Rsense) x (Vref / 2.048), where Rgain is the gain resistor, Rsense is the sense resistor, and Vref is the reference voltage.
  • The maximum current that the INA821 can measure depends on the sense resistor value and the supply voltage. Typically, it can measure up to ±50A with a 1mΩ sense resistor and a 3.3V supply voltage.
