AN-609: Chopping on Sigma-Delta ADCs:
AN-609 - Analog Devices Application Notes (Circuit / schematic design added
6/06) Chopping is a technique that can be used to cancel offset voltages and
other low frequency errors. This Application Note outlines how chopping is implemented
on the AD7708/AD7718,AD7709,AD7719,AD7782/AD7783 high resolution Sigma-Delta ADCs and
discusses the resulting benefits it brings.
Application Considerations and Circuits for a New Chopper-Stabilized Op
Amp: AN9 - Linear Technology - A discussion of
circuit, layout and construction considerations for low level DC circuits includes
error analysis of solder, wire and connector junctions. Applications include
sub-microvolt instrumentation and isolation amplifiers, stabilized buffers and
comparators and precision data converters.
