OPA604AU Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the OPA604AU is ±2V to ±18V, with a maximum differential voltage of 36V.
  • To ensure stability in a unity-gain configuration, add a 10nF to 22nF capacitor in parallel with a 1kΩ to 2kΩ resistor between the output and the inverting input.
  • The OPA604AU can drive up to 1nF of capacitive load without oscillation or instability.
  • To reduce noise and oscillations, use a low-ESR capacitor (e.g., ceramic or film) for power supply decoupling, and consider adding a 10Ω to 100Ω resistor in series with the output to reduce ringing.
  • While the OPA604AU can be used as a comparator, it's not recommended due to its relatively slow slew rate (2.5V/μs) and limited output current (±30mA). A dedicated comparator IC is generally a better choice.
