Datasheet Summary
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...
