The Hl-DAC80V is a monolithic direct replacement for the
popular DAC80 and AD DAC80. The HI-DAC85V is a mono-
lithic direct replacement for the popular DAC85 and AD
DAC85 as well as the HI-5685V. Single chip construction
along with several design innovations make the Hl-DAC80V
the optimum choice for low cost, high reliability applications.
Intersil’ unique Dielectric Isolation (Dl) processing reduces
internal parasitics resulting in fast switching times and mini-
mum glitch. On board span resistors are provided for good
tracking over temperature, and are laser trimmed to high
accuracy.
Internally the Hl-DAC80V/HI-DAC85V eliminates code
dependent ground currents by routing current from the posi-
tive supply to the internal ground node, as determined by an
auxiliary R2R ladder. This results in a cancellation of code
dependent ground currents allowing virtually zero variation
in current through the package common, pin 21.
The Hl-DAC80V is available as a voltage output device which
is guaranteed over the 0^oC to 75^oC temperature range. The
HI-DAC85V is available as a voltage output device which is
guaranteed over the -25^oC to 85^oC temperature range. It
includes a buried zener reference featuring a low temperature
coefficient as well as an on board operational amplifier. The
Hl-DAC80V requires only two power supplies and will operate
in the range of ± (11.4V to 16.5V).
