AD822BRZ Frequently Asked Questions (FAQs)

  • The AD822BRZ can handle a maximum common-mode voltage of ±200 mV, but it's recommended to keep it within ±100 mV for optimal performance.
  • The gain of the AD822BRZ can be optimized by selecting the appropriate gain resistor (RG) value. A smaller RG value results in higher gain, while a larger RG value results in lower gain. Use the formula RG = 50 kΩ / (G - 1) to calculate the optimal RG value for your desired gain (G).
  • The recommended power supply voltage for the AD822BRZ is ±2.3 V to ±18 V, with a maximum differential voltage of 36 V.
  • To reduce noise and EMI, use a low-pass filter at the input, keep the input wires short and twisted, and use a ground plane to shield the circuit. Additionally, consider using a ferrite bead or a common-mode choke to filter out high-frequency noise.
  • Yes, the AD822BRZ can be used in a single-supply application, but it requires a voltage reference (VREF) to set the output common-mode voltage. The VREF pin should be connected to a voltage divider or a voltage reference IC to set the desired output common-mode voltage.
