1ppm Settling Time Measurement for a Monolithic 18-Bit DAC

January 02, 2012 // By Jim Williams, Linear Technology
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. New componentshave 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 specifi cations approach or equal previous converters at significantly lower cost.
