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.

The AD8387 is fabricated on ADIs fast bipolar, 26 V XFCB  
process, providing fast input logic, bipolar DACs with trimmed  
accuracy and fast settling, high voltage, precision drive  
amplifiers on the same chip.

The AD8387 dissipates 1.34 W nominal static power. The  
AD8387 is offered in an 80-lead TQFP E-pad package and  
operates over the commercial temperature range of 0°C to  
+85°C.
