ULN2803ADW

The ULN2803ADW is a high-voltage, high-current Darlington transistor array produced by Texas Instruments. It features eight Darlington transistor pairs, each capable of delivering up to 500 mA of collector current. Designed for switching inductive loads, this chip incorporates common-cathode clamp diodes at its output terminals to absorb inductive voltage spikes generated during transistor switching, thereby protecting the transistors from damage.

The ULN2803ADW comes in a surface-mount DW-type package and offers a compact solution for driving high output currents. It is suitable for use in applications that require high current output and inductive load protection. The high integration of this device reduces the need for external components, simplifying circuit design and lowering costs. With its clear and explicit pin functions, interfacing with the ULN2803ADW becomes straightforward and convenient.

In addition, the ULN2803ADW is specifically designed to operate directly with TTL or 5-V CMOS devices, featuring a 2.7-kΩ series base resistor for each Darlington pair. It offers a wide operating temperature range of -40°C to 85°C and is available in various packaging options, including tubes of 20, tubes of 40, and reels of 2000.

Overall, the ULN2803ADW is a versatile and powerful high-current driver chip that is well-suited for a wide range of applications, including computers, industrial equipment, and consumer products.
