Overview

AS1109 Constant-Current, 8-Bit LED Driver with Diagnostics 1 General Description The AS1109 is designed to drive up to 8 LEDs through a fast serial interface and features 8 output constant current drivers and an onchip 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 100mA/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 inte...
