AN-609: Chopping on Sigma-Delta ADCs - AN-609 Analog Devices Application Notes (app note added 6/06) Chopping is a technique that can be used to cancel offset voltages and or low frequency errors. This Application Note outlines how chopping is implemented on AD7708/AD7718,AD7709,AD7719,AD7782/AD7783 high resolution Sigma-Delta ADCs and discusses resulting benefits it brings.

Chopping Reduces Reference’s Supply Current - 04/10/97 EDN-Design Ideas The 10V precision reference, IC3, in Figure 1 has temperature drift of approximately 0.6 ppm/�C and good long-term stability. However, because of its zener-based design, this reference needs more than 4 mA of supply current. To reduce this current, the circuit in Figure 1 supplies the reference with chopped power. This scheme lowers the mean supply.... [Design Idea by Hartmut Henkel, von Hoerner & Sulger GmbH, Schwetzingen, Germany]
