INA828IDR Frequently Asked Questions (FAQs)

  • The INA828IDR can handle input voltages up to ±650mV, but it's recommended to keep the input voltage within ±500mV to ensure accurate measurements.
  • The gain resistor (Rg) should be chosen based on the desired gain and the input voltage range. A smaller Rg value results in higher gain, but may also increase noise. A larger Rg value results in lower gain, but may also reduce noise. Consult the datasheet for a gain resistor calculation formula.
  • The REF pin is a reference voltage input that allows the INA828IDR to provide a ratiometric output. Connect the REF pin to a stable voltage reference (e.g., a voltage regulator output) to ensure accurate measurements. If not used, connect the REF pin to the VCC pin.
  • Use a low-pass filter (e.g., RC filter) at the input stage to filter out high-frequency noise. Additionally, consider using a shielded cable and a ground plane to reduce electromagnetic interference (EMI).
  • The INA828IDR can drive up to 10mA of output current. However, it's recommended to keep the output current below 5mA to ensure accurate measurements and prevent overheating.
