Zero-drift amplifiers dynamically correct their offset voltage and reshape noise density. Two commonly used types—auto-zero amplifiers and choppers—achieve nanovolt-level offsets and extremely low ...

One of my first jobs as a freshly minted graduate engineer involved the maintenance of a set of analogue chart recorders. They were museum pieces by the early 1990s: a motorized roll of graph paper ...

Assuming the position of the industry's lowest noise auto-zero amp, the AD8628 provides a noise figure of 0.5 µVp-p from 0 Hz to 10 Hz. Commonly called a chopper-stabilized amplifier, the device has a ...

Analog Devices Inc., a supplier of amplifiers, unveiled the industry's first digitally programmable, signal-conditioning auto-zero amplifier for strain-bridge and other sensors that are widely used in ...
