PRODUCT DESCRIPTION
The ADDAC80 Series is a family of low cost 12-bit digital-to-
analog converters with both a high stability voltage reference
and output amplifier combined on a single monolithic chip.
The ADDAC80 Series is recommended for all low cost 12-bit D/A
converter applications where reliability and cost are of paramount
importance.
Advanced circuit design and precision processing techniques
result in significant performance advantages over conventional
DAC80 devices. Innovative circuit design reduces the total
power consumption to 300 mW, which not only improves reli-
ability, but also improves long term stability.
The ADDAC80 incorporates a fully differential, nonsaturating
precision current switching cell structure which provides greatly
increased immunity to supply voltage variation. This same struc-
ture also reduces nonlinearities due to thermal transients as the
various bits are switched; nearly all critical components operate
at constant power dissipation. High stability, SiCr thin film
resistors are trimmed with a fine resolution laser, resulting in
lower differential nonlinearity errors. A low noise, high stability,
subsurface Zener diode is used to produce a reference voltage
with excellent long term stability, high external current capabil-
ity and temperature drift characteristics which challenge the
best discrete Zener references.
The ADDAC80 Series is available in three performance grades
and three package types. The ADDAC80 is specified for use
over the 0
°C to 70°C temperature range and is available in
both plastic and ceramic DIP packages. The ADDAC85 and
ADDAC87 are available in hermetically sealed ceramic packages
and are specified for the –25
°C to +85°C and –55°C to +125°C
temperature ranges.
PRODUCT HIGHLIGHTS
1. The ADDAC80 series of D/A converters directly replaces all
other devices of this type with significant increases in performance.
2. Single chip construction and low power consumption pro-
vides the optimum choice for applications where low cost
and high reliability are major considerations.
3. The high speed output amplifier has been designed to settle
within 1/2 LSB for a 10 V full scale transition in 2.0
s, when
properly compensated.
4. The precision buried Zener reference can supply up to 2.5 mA
for use elsewhere in the application.
5. The low TC binary ladder guarantees that all units are mono-
tonic over the specified temperature range.
6. System performance upgrading is possible without redesign.
