ULN2004AD Frequently Asked Questions (FAQ)

  • The ULN2004AD can sink up to 500mA per output, but it's recommended to limit it to 350mA for reliable operation.

  • Use a flyback diode (e.g., 1N4007) in parallel with the inductive load to absorb the back-EMF. This is especially important when driving relays, solenoids, or motors.

  • The ULN2004AD 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, but be aware that the ULN2004AD is a Darlington transistor array, which has a higher voltage drop than a standard transistor. This may affect the brightness of the LEDs. Use a current-limiting resistor to prevent overheating.

  • Use the formula: Pd = (Vin - Vout) x Iout x N, where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and N is the number of outputs. Ensure the total power dissipation does not exceed the maximum rating of 1.5W.
