INA281A3IDBVT Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the input pins is 26.4V, which is the absolute maximum rating. However, for normal operation, the input voltage should be within the range of 0V to 24V.
  • The gain of the amplifier is fixed at 20V/V. This means that the output voltage will be 20 times the input voltage. For example, if the input voltage is 1V, the output voltage will be 20V.
  • The REF pin is the reference voltage input for the amplifier. It sets the output voltage level when the input voltage is zero. Typically, the REF pin is connected to a voltage divider from the supply voltage to set the output voltage level to mid-supply.
  • Yes, the INA281A3IDBVT can be used as a differential amplifier. The device has a differential input stage that can amplify the difference between the two input voltages. However, the common-mode rejection ratio (CMRR) is not specified in the datasheet, so it's essential to ensure that the input common-mode voltage is within the specified range.
  • The power consumption of the INA281A3IDBVT depends on the supply voltage and the output load. The typical quiescent current is 1.2mA, and the maximum power consumption is 30mW. However, the actual power consumption will be higher when the output is loaded.
