DESCRIPTION  
BPO B  
The DAC4814 is one in a family of dual and quad 12-  
bit digital-to-analog converters. Serial, 8-bit, 12-bit  
interfaces are available.

The DAC4814 is complete. It contains CMOS logic,  
switches, a high-performance buried-zener reference,  
and low-noise bipolar output amplifiers. No external  
components are required for either unipolar 0 to 10V,  
0 to –10V, or bipolar ±10V output ranges.

The DAC4814 has a high-speed serial interface  
capable of being clocked at 10MHz. Serial data are  
clocked DAC D MSB first into a 48-bit shift register,  
then strobed into each DAC separately or simulta-  
neously as required. The DAC has an asynchronous  
clear control for reset to unipolar or bipolar zero  
depending on the mode selected. This feature is useful  
for power-on reset or system calibration. The DAC4814  
is packaged in a 28-pin plastic DIP rated for the –40°C  
to +85°C extended industrial temperature range.
