GENERAL DESCRIPTION
The AD8387 DecDriver provides dual, fast latched, 12-bit decimating input, which drives 12 high voltage outputs. Twelve-bit input words are loaded into 12 separate high speed, bipolar DACs sequentially. Flexible digital input format allows more than one AD8387 to be used in parallel for higher resolution displays. The output signal can be adjusted for dc reference, signal inversion, and contrast for maximum flexibility.
