PRODUCT DESCRIPTION  
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 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 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.
