INA281B3IDBVR Frequently Asked Questions (FAQ)
-
The maximum voltage that can be applied to the input pins is 26.5V, 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 increases or decreases from the nominal operating temperature.
-
Yes, the INA281 can be used with a single-supply voltage. However, the input common-mode voltage range is limited to VCC - 1.5V to VCC + 0.5V, where VCC is the supply voltage. This means that the input voltage must be within this range to ensure proper operation.
-
To minimize noise and interference with the INA281, it is recommended to follow good PCB layout practices, such as keeping the input traces short and away from noise sources, using a ground plane, and placing bypass capacitors close to the device. Additionally, it is recommended to use a shielded cable or twisted pair for the input connections.
