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.
