OPA827AIDGKR datasheet by Texas Instruments

OPA827AIDGKR Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the OPA827AIDGKR?
  The maximum power dissipation of the OPA827AIDGKR is 670mW, which is calculated based on the maximum junction temperature (TJ) of 150°C and the thermal resistance (θJA) of 125°C/W.
• How do I ensure stability when using the OPA827AIDGKR in a high-gain configuration?
  To ensure stability, it's recommended to use a compensation capacitor (CC) between the output and the inverting input pins. The value of CC depends on the gain and bandwidth requirements of the application. A good starting point is a 10pF to 22pF capacitor.
• What is the recommended layout and routing for the OPA827AIDGKR to minimize noise and oscillations?
  To minimize noise and oscillations, it's recommended to use a star-ground configuration, keep the input and output traces short and away from each other, and use a solid ground plane. Additionally, decouple the power supplies with 0.1uF to 1uF capacitors and use a low-ESR capacitor for the output stage.
• Can I use the OPA827AIDGKR in a single-supply configuration?
  Yes, the OPA827AIDGKR can be used in a single-supply configuration. However, the input common-mode voltage range is limited to VCC-1.5V to VCC+0.5V. To ensure proper operation, the input signal should be biased within this range.
• How do I protect the OPA827AIDGKR from overvoltage and ESD?
  To protect the OPA827AIDGKR from overvoltage and ESD, it's recommended to use a voltage clamp or a transient voltage suppressor (TVS) diode at the input pins. Additionally, use a series resistor and a capacitor to filter out high-frequency noise and transients.
