DAC729
DESCRIPTION
The DAC729 sets the standard in very high accuracy
digital-to-analog conversion. It is supplied from the
factory at a guaranteed linearity of 16 bits, and is user-
adjustable to 18-bit linearity (1LSB = FSR/262144).
To attain this high level of accuracy, the design takes
advantage of Burr-Brown’s thin-film monolithic DAC
process, dielectric op amp process, hybrid capabilities,
and advanced test and laser-trim techniques.
The DAC729 hybrid layout is specifically partitioned
to minimize the effects of external load-current-
induced thermal errors. The op amp design consists of
a fast settling precision op amp with a current buffer
within the feedback loop. This buffer isolates the load
from the precision op amp, which results in a fast
settling (8
μ
s to 16 bits) output. The standard 40-pin
package offers full hermeticity, contributing to the
excellent reliability of the DAC729.
