INA281A5IDBVR Frequently Asked Questions (FAQs)

  • The maximum voltage that can be applied to the input pins is 26V, which is the absolute maximum rating. However, for normal operation, the recommended maximum input voltage is 24V.
  • The gain error of the INA281 can be calculated using the formula: Gain Error (%) = (Vout/Vin - Gain) / Gain * 100, where Vout is the output voltage, Vin is the input voltage, and Gain is the specified gain of the device (e.g. 1, 2, 5, etc.).
  • The INA281's accuracy is affected by temperature, with a typical temperature coefficient of ±50 ppm/°C for the gain error and ±10 ppm/°C for the offset voltage. This means that the device's accuracy will degrade as the temperature deviates from the nominal operating temperature of 25°C.
  • Yes, the INA281 can be used as a differential amplifier by connecting the input pins in a differential configuration. However, the device is optimized for single-ended input applications, and the common-mode rejection ratio (CMRR) may not be as high as a dedicated differential amplifier.
  • To minimize noise and ensure accurate operation, it is recommended to follow a star-ground layout, keep the input traces short and away from noise sources, and use a solid ground plane. Additionally, the output capacitor should be placed close to the output pin and connected to a low-impedance node.
