LM747J/883 Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the LM747J/883 is 1.4W, which is calculated based on the maximum junction temperature (Tj) of 150°C and the thermal resistance (RθJA) of 125°C/W.
  • Yes, the LM747J/883 is designed to operate in high-temperature environments, with an operating temperature range of -55°C to 125°C. However, the device's performance may degrade at extreme temperatures.
  • To ensure stability, make sure to follow proper PCB layout practices, use a stable power supply, and add decoupling capacitors as close to the op-amp as possible. Additionally, consider adding a compensation capacitor (e.g., 10-100pF) between the output and the inverting input to improve stability.
  • The recommended input impedance for the LM747J/883 is greater than 1kΩ to ensure optimal performance. Lower input impedances may lead to reduced gain and increased distortion.
  • While the LM747J/883 can be used as a comparator, it's not the most suitable choice due to its relatively slow slew rate (0.5V/μs) and limited bandwidth (1MHz). Consider using a dedicated comparator IC for high-speed or high-precision applications.
