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.
