The AD8388 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 AD8388s to be used in parallel for higher resolution displays.

The AD8388 is fabricated on Analog Devices' XFHV, fast bipolar 26 V process, providing fast input logic bipolar DACs with trimmed accuracy and fast settling, high voltage, precision drive amplifiers on the same chip. The AD8388 dissipates 743 mW nominal static power. The STBY pin reduces power to a minimum, with fast recover.
