The AD8380 provides a fast, 10-bit latched decimating digital input that drives 6-channel high voltage drive outputs. The voltage outputs are laser trimmed for high absolute accuracy. The 10- bit input word is sequentially muxed into six separate high speed, bipolar DACs. Flexible digital input formats, allow several AD8380s to be used in parallel for higher resolution displays. STSQ/CS, in conjunction with 3-bit addressable channel-loading pins, allows loading of the digital words either sequentially or randomly, and R/L control sets loading as either left to right, or vice versa. Six-channel high voltage output drivers drive to within 1.3 V of the rails. The output signal can be adjusted for dc signal reference, signal inversion or contrast for maximum flexibility. The AD8380 is fabricated on ADI's XFCB26 fast bipolar 26 V process, providing fast input logic, trimmed accuracy bipolar DACs and fast settling, high voltage precision drive amplifiers on the same chip. The AD8380 dissipates nominally 0.55 W of static power. STBY pin reduces power to a minimum, with fast recovery. The AD8380 is offered in a 44-lead 10 x 10 x 2.0 mm MQFP package and operates over the commercial temperature range of 0°C to +85°C.
