AS1113 16-Channel LED Driver

The AS1113 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. Output current.

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. Output current is adjustable (up to 50mA/channel) using an external resistor (REXT). The serial interface with Schmitt trigger inputs includes an integrated shift register. Additionally, an internal data register stores the currently displayed data. The device features integrated diagnostics for overtemperature, open-LED, and shorted-LED condi.
