AD8387

High Performance, 12-Bit, 12-Channel Decimating, LCD DecDriver® AD8387 05653-001 FEATURES High accuracy, high-resolution voltage outputs 1 mV channel matching 12-bit input resolution Laser-trimmed outputs Fast settling, high voltage drive 35 ns settling time to 0.25% into 150 pF load Slew rate 420 V/μs Outputs to within 1.3 V of supply rails High update rates Fast, 110 MHz clock Programmable video reference (brightness) and full-scale (contrast) output levels Flexible logic INV bit reverses polarity of video signal R/L reverses loading order of data ISW selects frame/row or column/dot inversion DSW selects single or dual data bus mode Output short-circuit protection 3.3 V logic, 11 V to 18 V analog supplies Available in 80-lead, 12 mm × 12 mm, TQFP E-pad APPLICATIONS LCD microdisplay driver GENERAL DESCRIPTION The AD8387 DecDriver provides dual, fast latched, 12-bit decimating input, which drives 12 high voltage outputs. Twelvebit input words are loaded into 12 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 1.34 W nominal static p...
