INA322EA/2K5 datasheet by Texas Instruments

INA322EA/2K5 Frequently Asked Questions (FAQs)

• What is the maximum voltage that can be applied to the input pins?
  The maximum voltage that can be applied to the input pins is 40V, but it's recommended to keep it below 36V to ensure accurate measurements.
• How do I calculate the power consumption of the INA322EA/2K5?
  The power consumption can be calculated by multiplying the supply voltage (VCC) by the quiescent current (Iq). For example, if VCC is 3.3V and Iq is 350uA, the power consumption would be 3.3V * 350uA = 1.155mW.
• What is the effect of temperature on the accuracy of the INA322EA/2K5?
  The INA322EA/2K5 has a temperature coefficient of ±0.05% per °C, which means that the accuracy of the device can vary by ±0.05% for every degree Celsius change in temperature. This can affect the overall accuracy of the measurements.
• Can I use the INA322EA/2K5 to measure negative voltages?
  No, the INA322EA/2K5 is not designed to measure negative voltages. It can only measure positive voltages up to 40V. If you need to measure negative voltages, you may need to use a different device or add additional circuitry to convert the negative voltage to a positive voltage.
• How do I ensure the accuracy of the INA322EA/2K5 over time?
  To ensure the accuracy of the INA322EA/2K5 over time, it's recommended to follow proper PCB layout and design guidelines, use a stable power supply, and minimize noise and interference in the system. Additionally, calibration and trimming of the device may be necessary to maintain accuracy over time.
