Description:
The DM13A 16 Channel Constant Current Driver IC – Pack of 5 offers a compact and efficient solution for controlling multiple LEDs or segment displays with constant current output. Designed for use in digital signage, LED matrices, and general-purpose light driving, the DM13A allows precise current regulation per channel, ensuring consistent brightness regardless of supply voltage variation.
Each IC supports 16 constant current sink outputs with a built-in shift register and latch for serial data communication. With cascading capability via serial data out, multiple DM13As can be daisy-chained to control larger LED arrays. Compatible with TTL/CMOS logic levels and clocked at up to 25MHz, this IC is a reliable choice for projects requiring stable LED output and fine control of current levels. Each pack contains five ICs in DIP-24 format, suitable for breadboard or through-hole PCB applications.
