TL081CD datasheet by STMicroelectronics

TL081CD Frequently Asked Questions (FAQs)

• What is the maximum power supply voltage that can be applied to the TL081CD?
  The maximum power supply voltage that can be applied to the TL081CD is 36V. Exceeding this voltage can cause damage to the device.
• Can the TL081CD operate from a single power supply?
  Yes, the TL081CD can operate from a single power supply. However, the input common-mode voltage range is limited, and the output voltage swing is reduced when operating from a single supply.
• What is the minimum output current that the TL081CD can source or sink?
  The TL081CD can source or sink up to 10mA of output current. Attempting to draw more current than this can cause the output voltage to drop or the device to overheat.
• How do I ensure stability when using the TL081CD in a feedback loop?
  To ensure stability, it's essential to follow proper PCB layout practices, use a compensation capacitor (if necessary), and ensure that the feedback loop has a sufficient phase margin. The datasheet provides guidance on compensation capacitor values and layout considerations.
• Can the TL081CD be used in audio applications?
  Yes, the TL081CD can be used in audio applications, but it's not the best choice due to its relatively high noise floor and limited bandwidth. For audio applications, consider using a low-noise, high-bandwidth op-amp like the OPA2134 or the LM4562.
