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.
