UA747CNE4 Frequently Asked Questions (FAQs)

  • The maximum power dissipation of the UA747CNE4 is 500 mW, which is limited by the package thermal resistance and the ambient temperature.
  • While the UA747CNE4 can be used as a comparator, it's not recommended due to its relatively slow slew rate (0.5 V/μs) and limited bandwidth (1.5 MHz). TI recommends using a dedicated comparator like the LM339 or LM2901 for comparator applications.
  • To ensure stability, make sure to follow proper compensation techniques, such as adding a capacitor in parallel with the feedback resistor to reduce the gain-bandwidth product. Additionally, ensure that the feedback loop has a sufficient phase margin (>45°) to prevent oscillations.
  • The input impedance of the UA747CNE4 is typically around 2 MΩ, which is relatively high. This makes it suitable for use in high-impedance circuits, such as audio amplifiers and instrumentation amplifiers.
  • Yes, the UA747CNE4 can be used in a single-supply configuration, but it's essential to ensure that the input common-mode voltage is within the specified range (VCC-1.5V to VCC+1.5V). Additionally, the output voltage swing will be limited to around 1.5V below the positive supply rail.
