Abstract

The subject disclosure provides a temperature-compensated voltage reference in a module that contains a digital-to-analog converter (DAC). The DAC output voltage tolerance, which is primarily a function of the tolerance and tracking of its current sources, must be minimized to reduce step-to-step adjustment tolerance.
