1ppm settling time measurement for a monolithic 18-bit DACWhen 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 specifically, 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 D/A 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 ...
