The AS1106 from ams AG is an 8 x 8 LED Display driver IC that is ideal for bar-graph displays, instrument-panel meters, LED matrix displays, dot matrix displays, set-top boxes, white goods, professional audio equipment, industrial controllers and panel meters, and medical equipment applications. It requires an input voltage of 2.7 - 5.5 V. This LED driver consists of an integrated BCD code-B/HEX decoder, multiplex scan circuitry, software reset function, external clock, segment and display drivers, and 64-bit memory. It stores the LED settings in the internal memory, thereby eliminating the need for continuous device reprogramming. This LED driver uses only one external resistor (RSET) to control and set the amount of current flowing through the LED display along with special analog and digital techniques to adjust the LED. It can be programmed to use the internal code-B/HEX decoder to display numeric digits or to directly address each segment.
This LED driver IC provides segment blinking control, which can be synchronized across multiple drivers along with several test modes to enable easy application debugging. It is available in a surface-mount package that measures 15.40 x 10.30 mm.
