1ppm Settling Time Measurement for a Monolithic 18-Bit DAC &mdash AN120
PDF, 2.1 Mb, File published: Mar 10, 2010
Performance requirements for instrumentation, function generation, inertial navigation systems, trimming, calibrators, ATE, medical apparatus and other precision applications are beginning to eclipse capabilities of 16-bit data converters. More specifi cally, 16-bit digital-to-analog converters (DACs) have been unable to provide required resolution in an increasing number of ultra-precision applications.

1ppm Settling Time Measurement
for a Monolithic 18-Bit DAC
When Does the Last Angel Stop Dancing on a Speeding Pinhead?
Jim Williams
Introduction
Performance requirements for instrumentation, function
generation, inertial navigation systems, trimming, calibrators, ATE, medical apparatus and other precision applications
are beginning to eclipse capabilities of 16-bit data converters. More speciп¬Ѓcally, 16-bit digital-to-analog converters
(DACs) have been unable to provide required resolution in
an increasing number of ultra-precision applications.
New components (see Components for 18-bit Digitalto-Analog Conversion, page 2) have made 18-bit DACs
a practical design alternative1. These ICs provide 18-bit
performance at reasonable cost compared to previous
modular and hybrid technologies. The monolithic DACs
DC and AC speciп¬Ѓcations approach or equal previous
converters at signiп¬Ѓcantly lower cost.
DAC Settling Time
DAC DC speciп¬Ѓcations are relatively easy to verify. Measurement techniques are well understood, albeit often tedious.
AC speciп¬Ѓcations require more sophisticated approaches
to produce reliable information. In particular, the settling
time of a DAC and its output ampliп¬Ѓer is extraordinarily …
