10-Bit, 6-Channel Decimating LCD DecDriver® With Level Shifters
The AD8384 DecDriver provides a fast, 10-bit, latched, decimating digital input that drives six high voltage outputs. 10-bit input words are loaded sequentially into six separate high speed, bipolar DACs Flexible digital input format allows several AD8384s 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 input, 8-bit DACs are integrated to provide dc reference signals. DAC addresses and 8-bit data are loaded in one 12-bit serial word.
The AD8384 is fabricated on the 26 V, fast, bipolar XFHV process developed by Analog Devices, Inc. This process provides fast input Logic bipolar DACs with trimmed accuracy and fast settling, high voltage, precision drive Amplifiers on the same chip.
The AD8384 dissipates 1.1 W nominal static power.
The AD8384 is offered in an 80-lead 12 mm 12 mm TQFP E-pad package and operates over the 0C to 85C commercial temperature range.
