LM148J/883 datasheet by Texas Instruments

LM148J/883 Frequently Asked Questions (FAQs)

• What is the maximum power dissipation of the LM148J/883?
  The maximum power dissipation of the LM148J/883 is 1.4W. However, it's recommended to derate the power dissipation to ensure reliable operation.
• How do I ensure stability in the LM148J/883 op-amp?
  To ensure stability, it's essential to follow proper PCB layout practices, use a bypass capacitor (e.g., 0.1uF) between the power supply pins, and avoid capacitive loads.
• What is the recommended operating temperature range for the LM148J/883?
  The recommended operating temperature range for the LM148J/883 is -55°C to 125°C. However, the device can operate up to 150°C with reduced performance.
• Can I use the LM148J/883 as a comparator?
  Yes, the LM148J/883 can be used as a comparator, but it's not recommended due to its op-amp architecture. For comparator applications, consider using a dedicated comparator IC like the LM339.
• How do I reduce noise in my circuit when using the LM148J/883?
  To reduce noise, use a low-pass filter, add a noise-reducing capacitor (e.g., 10nF) between the input pins, and ensure a clean power supply with minimal ripple.
