PRODUCT DESCRIPTION
The AD8380 provides a fast, 10-bit latched decimating digital
input that drives 6-channel high voltage drive outputs. 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. 6-channel high voltage output drivers drive to within
1.3 V of the rails to rated settling time. 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 × 10 × 2.0 mm MQFP
package and operates over the commercial temperature range of
0°C to 85°C.
