RC4559D datasheet by Texas Instruments

RC4559D Frequently Asked Questions (FAQs)

• What is the maximum power supply voltage that can be applied to the RC4559D?
  The maximum power supply voltage that can be applied to the RC4559D is ±18V. Exceeding this voltage can cause damage to the device.
• Can the RC4559D be used in single-supply applications?
  Yes, the RC4559D can be used in single-supply applications, but the input common-mode voltage range is limited to within 2V of the positive supply rail. Additionally, the output voltage swing will be reduced in single-supply operation.
• How do I ensure stability when using the RC4559D in a unity-gain configuration?
  To ensure stability in a unity-gain configuration, a capacitor (typically 10nF to 100nF) should be connected between the output and the inverting input to prevent oscillation. This is known as a 'compensation capacitor'.
• What is the maximum output current that the RC4559D can supply?
  The maximum output current that the RC4559D can supply is ±10mA. Exceeding this current can cause the device to overheat or become unstable.
• Can the RC4559D be used in audio applications?
  Yes, the RC4559D is suitable for audio applications due to its high gain-bandwidth product, low noise, and low distortion. However, it may not be the best choice for high-fidelity audio applications due to its relatively high noise floor and limited output current capability.
