Use of Digital-to-Analog Converters in Circuit Design

High-quality digital-to-analog converters are now available at relatively low prices and can be used to advantage in many instrumentation applications. The examples that are considered in this paper include a very general transducer output linearizing analog-to-digital converter, an analog multiplier and a more general signal processing circuit that has an output E0 of the form E0 = KEs1f(Es2) where K is a constant, Es1 and Es2 are input voltages and f(Es2) is any prescribed function of Es2.
