APPLICATION NOTE 4539
Precise Calibration of Dual-Slope ADCs


Abstract:This circuit calibrates ADCs on-the-fly, using analog switches to configure the setup properly for obtaining the zero and
span output codes.

A similar version of this article appeared in the December 31, 2007 issue of EE Times magazine.

Handheld devices for measuring toxic gas, blood glucose, etc. are increasingly popular, and their low cost has made them
throwaway devices, to be discarded when the battery or the sensor expires. Typical devices include a lithium (Li) primary cell, a
sensor, an A/D converter (ADC), conditioning ci……
