GENERAL DESCRIPTION

The AD8386 provides a fast, 10-bit, latched, decimating digital

input that drives 12 high voltage outputs. Input words with

10 bits are loaded sequentially into 12 separate high speed,

bipolar DACs. Flexible digital input format allows several

AD8386s to be used in parallel in high resolution displays.

The output signal can be adjusted for dc reference, signal

inversion, and contrast for maximum flexibility.

The AD8386 is fabricated on ADI’s fast bipolar, 26 V XFHV

process, which provides fast input logic, bipolar DACs with

trimmed accuracy and fast settling, high voltage, precision

drive amplifiers on the same chip.

The AD8386 dissipates 1.4 W nominal static power.

The AD8386 is offered in a 64-lead 9 mm × 9 mm LFCSP_VQ

package and operates over the commercial temperature range of

0°C to 85°C.
