AD820ARZ Frequently Asked Questions (FAQ)

  • The maximum power dissipation of the AD820ARZ is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.

  • To ensure stability in a unity-gain configuration, it's recommended to add a capacitor (typically 10nF to 100nF) between the output and the inverting input to compensate for the op-amp's internal capacitance and ensure a stable phase margin.

  • To minimize noise and EMI, it's recommended to keep the input and output traces short and away from each other, use a ground plane, and avoid running sensitive traces near the op-amp's power pins. Additionally, decoupling capacitors (e.g., 0.1uF) should be placed close to the op-amp's power pins.

  • While the AD820ARZ can be used as a comparator, it's not the most suitable choice due to its relatively slow slew rate (0.5V/μs) and limited output current (±20mA). A dedicated comparator like the AD790 or AD8561 would be a better choice for most applications.

  • The AD820ARZ has a relatively high input bias current (±500nA) and offset voltage (±2mV). To minimize their impact, use a high-impedance input source, add a bias current compensation resistor, and consider using a chopper-stabilized op-amp like the AD8639 for applications requiring high accuracy.
