RC4558PSR Frequently Asked Questions (FAQs)

• What is the maximum power supply voltage for the RC4558PSR?
  The maximum power supply voltage for the RC4558PSR is ±18V. Exceeding this voltage can damage the device.
• Can I use the RC4558PSR in a single-supply configuration?
  Yes, the RC4558PSR can be used in a single-supply configuration. However, the input common-mode voltage range is limited, and the output voltage swing may be reduced.
• What is the input impedance of the RC4558PSR?
  The input impedance of the RC4558PSR is typically around 2MΩ, but it can vary depending on the specific application and operating conditions.
• Can I use the RC4558PSR as a comparator?
  While the RC4558PSR can be used as a comparator, it's not the best choice due to its relatively slow slew rate and limited output current capability. A dedicated comparator IC would be a better option.
• How do I reduce noise and oscillations in my RC4558PSR circuit?
  To reduce noise and oscillations, ensure proper power supply decoupling, use a low-pass filter at the input, and add a capacitor in parallel with the feedback resistor to reduce high-frequency gain.
