• Supports up to 16 independent output channels for individual LED control
• Capable of delivering up to 100mA output current per channel
• Operates on a low voltage supply ranging from 3V to 5.5V

Applications

• Signage displays
• LED matrix panels
• Digital signage solutions

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for End-of-Life notices, as the related AS1110 series has been subject to production change notifications. Ensure the specific suffix matches required packaging and thermal specifications before ordering.

Selection Notes

Select this component for designs requiring precise linear current regulation for LED arrays. Consider the 24-SSOP package constraints for PCB layout. Evaluate thermal dissipation requirements given the linear topology. Verify that the 16-channel count aligns with the target display resolution needs.
