The DAC2814 is one in a family of dual and quad 12-
bit digital-to-analog converters. Serial, 8-bit, 12-bit
interfaces are available.
The DAC2814 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 DAC2814 has a high-speed serial interface
capable of being clocked at 10MHz. Serial data are
clocked DAC B MSB first into a 24-bit shift register,
then strobed into each DAC separately or simultaneously
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 DAC2814
is packaged in a 24-pin plastic DIP rated for the –40°C
to +85°C extended industrial temperature range.
High-stability laser-trimmed thin film resistors assure
high reliability and true 12-bit integral and differential
linearity over the full specified temperature range.
