AS1119-BWLT

General Description
The AS1110 is designed to drive up to 16 LEDs through a fast serial interface and features 16 output constant current drivers and an on-chip diagnostic read-back function.
The high clock-frequency (up to 50MHz), adjustable output current, and flexible serial interface makes the device perfectly suited for high-volume transmission applications.Key
