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.
