ULN2803
ULN2803 is an eight channel darlington array used to interface microcontrollers to high voltage, high current devices such as solenoids, lamps, relays etc. It has the capacity to drive 500mA into a single channel, upto 250mA per channel if four of the eight channels are active and 125 mA per channel if all the eight channels are active. It's output have clamp diodes for transient suppression to protect the low power microcontroller circuits. ULN2803 is commonly used for controlling large seven segment displays.
ULN2003
ULN2003 is a seven channel darlington array used to interface microcontrollers to high voltage, high current devices such as solenoids, lamps, relays etc. It has the capacity to drive 500mA into a single channel, upto 250mA per channel if four of the seven channels are active and 125 mA per channel if all the seven channels are active. It's output have clamp diodes for transient suppression to protect the low power microcontroller circuits.
The ULN2003 is the replacement for the ULN2803 when using the Prop-1 Trainer Board or when using P7 (Prop-1) or P15 (Prop-2 and Prop-SX) for serial communications with devices like the AP-8, DC-16, FC-4, and RC-4.
Hi, my name is marlin. Good article, this is very interesting and can increase my knowledge. thank you for sharing. always success

So what exactly the differences between the two ICs are ?
ReplyDeleteUln2803 has 8 channels.
ReplyDeleteUln2003 has 7 channels

ReplyDeleteso no actual difference in working? just difference in channels? how to decide which to use?
ReplyDeleteIs there a difference between a ULN2003AN and a ULN2003APG?
ReplyDeleteno difference is shown. it's just one and the same thing.
