ULN2003ADR Frequently Asked Questions (FAQ)
-
The ULN2003ADR can sink up to 500mA per output, but it's recommended to limit it to 350mA for reliable operation.
-
Power dissipation can be calculated using 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.
-
The minimum input voltage required is 4.5V, but it's recommended to use a minimum of 5V for reliable operation.
-
Yes, the ULN2003ADR can be used as a relay driver, but it's essential to ensure that the relay coil current is within the output current rating of the ULN2003ADR.
-
To protect the ULN2003ADR from back-EMF, use a flyback diode (such as 1N4001-1N4007) in parallel with the inductive load, with the anode connected to the output pin and the cathode connected to the supply voltage.
