Calibration ICs

Electronic calibration of equipment is reliable, cost effective, and flexible. To make design-in easier, Maxim offers DACs, digital potentiometers (pots), and voltage references specifically optimized for calibration applications. We have example circuits and application notes for electronic calibration.

Calibration Parts

A calibration part is an adjustable device with a predictable power-on-reset (POR) condition. Usually POR will read a value stored in nonvolatile (NV) memory in the device. Alternative devices that POR to zero, midscale, or full-scale can also be used in selected circuits. Maxim adds a C to signify calibration before a common acronym. Thus, CDPot is a calibration digital pot. CDAC is a calibration digital-to-analog converter. A CRef is a calibration voltage reference.
