PRODUCT DESCRIPTION  
The AD8382 DecDriver provides a fast, 12-bit latched decimat-  
ing digital input that drives six high voltage outputs.12-bit input  
words are sequentially loaded into six separate, high speed,  
bipolar DACs. A flexible digital input format allows several  
AD8382s to be used in parallel for higher resolution displays.  
STSQ synchronizes sequential input loading, XFR controls  
synchronous output updating, and R/L controls the direction of  
loading as either left-to-right or right-to-left. Six channels of  
high voltage output drivers drive to within 1.3 V of the rail. The  
output signal can be adjusted for dc reference, signal inversion,  
and contrast for maximum flexibility.  
The AD8382 is fabricated on Analog Devices’ XFHV, fast  
bipolar 26 V process, providing fast input logic bipolar DACs  
with trimmed accuracy and fast settling, high voltage, precision  
drive amplifiers on the same chip. The AD8382 dissipates  
743 mW nominal static power. The STBY pin reduces power to  
a minimum, with fast recovery.
