PRODUCT DESCRIPTION
The AD8382 DecDriver® provides a fast, 12-bit latched decimating 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.
