DESCRIPTION
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.
High-stability laser-trimmed thin film resistors assure
high reliability and true 12-bit integral and differential
linearity over the full specified temperature range.
