AD8385

The AD8385 provides a fast, 10-bit, latched decimating digital input that drives 12 high voltage outputs. 10-bit input words are loaded into 12 separate high speed, bipolar DACs sequentially. Flexible digital input format allows several AD8385s 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. Integrated level shifters convert timing signals from a 3 V timing controller to high voltage for LCD panel timing inputs. Two, serial, 8-bit DACs are integrated to provide dc reference signals. A 3-wire serial interface controls overload protection, output mode, and the serial DACs.

The AD8385 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 AD8385 dissipates 1.84 W nominal static power.

The AD8385 is offered in a 100-lead, 14 mm * 14 mm TQFP E-pad package and operates over the commercial temperature range of 0°C to 85°C.
