ULN2003AD Frequently Asked Questions (FAQs)

  • The ULN2003AD can sink up to 500mA per output, but it's recommended to limit it to 350mA for reliable operation.
  • Use a flyback diode (also known as a freewheeling diode) in parallel with the inductive load to absorb the back-EMF. This diode should be rated for the maximum voltage and current of the load.
  • The ULN2003AD can operate with input voltages as low as 3.5V, but it's recommended to use a minimum of 4.5V for reliable operation.
  • Yes, the ULN2003AD can be used to drive a relay, but make sure to choose a relay with a coil voltage and current rating that matches the ULN2003AD's output capabilities.
  • The power dissipation of the ULN2003AD can be calculated using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
