16-channel linear LED driver with shift register interface
The MAX6969ANG+ is a linear LED driver IC from Analog Devices, delivering 55 mA constant current per channel across 16 outputs. The shift register topology allows serial data input with latched outputs, making it suitable for multiplexed or static LED arrays in signage applications. The 24-DIP (0.300", 7.62mm) through-hole package simplifies prototyping and hand-assembly, with the 24-PDIP supplier package variant sharing the same footprint.
This span suits outdoor signage enclosures that see direct sunlight and cold starts, as well as interior commercial displays where the driver sits near warm LED arrays without active cooling. The through-hole DIP package limits board density but provides reliable solder joints under thermal cycling. For designs that need higher channel counts, multiple MAX6969ANG+ devices can be daisy-chained via the shift register data-out pin without additional logic.
