AD8386 Datasheet | Analog Devices

FEATURES High voltage drive To within 1.3 V of supply rails Output short-circuit protection High update rates Fast, 100 Ms/s 10-bit input data update rate Static power dissipation: 1.4 W Voltage-controlled video reference (brightness), offset, and full-scale (contrast) output levels INV bit reverses polarity of video signal 3.3 V logic, 9 V to 18 V analog supplies High accuracy voltage outputs Laser trimming eliminates the need for adjustments or calibration Flexible logic XFR allows parallel AD8386 operation Fast settling into capacitive loads 35 ns settling time to 0.25% into 150 p F load Slew rate 400 V/μs Available in 64-lead 9 mm × 9 mm LFCSP_VQ 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 mercial temperature range of 0°C to 85°C. 10-Bit, 12-Channel Output Decimating LCD Driver AD8386 FUNCTIONAL BLOCK DIAGRAM VRH 2 VRH VRL 10 DB(0:9) R/L GCTL 3 GSW TSW SDI 3 SCL SEN SVRH SVRL SVRL BIAS SCALING CONTROL TWO-STAGE 10-BIT LATCH DACs SEQUENCE CONTROL INV CONTROL 12-BIT SHIFT REGISTER 8-BIT DAC Figure...
