12-Bit, Low Cost, Monolithic D/A
Converter
The Hl-DAC80V is a monolithic direct replacement for the
popular DAC80 and AD DAC80. Single chip construction
along with several design innovations make the Hl-DAC80V
the optimum choice for low cost, high reliability applications.
Intersilâ unique Dielectric Isolation (Dl) processing reduces
internal parasitics resulting in fast switching times and
minimum glitch. On board span resistors are provided for
good tracking over temperature, and are laser trimmed to
high accuracy.
Internally the Hl-DAC80V eliminates code dependent ground
currents by routing current from the positive 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 0oC to 75oC 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).
