PRODUCT DESCRIPTION  
The AD8381 provides a fast, 10-bit latched decimating digital  
input, which drives six high voltage outputs. Ten-bit input  
words are sequentially loaded into six separate high-speed, bipolar  
DACs. Flexible digital input format allows several AD8381s 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 in rated settling  
time. The output signal can be adjusted for brightness, signal  
inversion and contrast for maximum flexibility.  
The AD8381 is fabricated on ADI’s proprietary, fast bipolar  
24 V process, providing fast input logic, bipolar DACs with  
trimmed accuracy and fast settling, high voltage precision drive  
amplifiers on the same chip.  
The AD8381 dissipates 570 mW nominal static power. STBY  
pin reduces power to a minimum, with fast recovery.  
The AD8381 is offered in a 48-lead 7 × 7 × 1.4 mm LQFP  
package and operates over the commercial temperature range of  
0°C to 85°C.
