High Performance 12-Bit, 12-Channel Output, Decimating LCD ®

The AD8387 DecDriver provides a fast, 12 bit, latched, decimating dual digital input, which drives twelve high voltage outputs. Twelve-bit input words are loaded into twelve separate high speed, bipolar DACs sequentially. Flexible digital input format allows more than one AD8387 to be used in parallel for higher resolution displays. The output signal can be adjusted for dc reference, signal inversion, and contrast for maximum flexibility.

The AD8387 is fabricated on ADI’s fast bipolar, 26 V XFCB process, providing fast input logic, bipolar DACs with trimmed accuracy and fast settling, high voltage, precision drive amplifiers on the same chip.

The AD8387 dissipates TBD W nominal static power. The AD8387 is offered in an 80-lead TQFP E-pad package and operates over the commercial temperature range of 0°C to +85°C.
