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
