TEMPERATURE_COMPENSATED_OFFSET_CONTROL

Published:2009/7/2 21:54:00 Author:May | From:SeekIC

Drift effects of offset adjustment are removed by deriving correction current from emitter-base voltage of PNP signal transistor to develop appropriate temperature compensatioll. Correction current is divided with conventional control pot used for adjusting offset voltage. Article gives design equations.-J.Graeme, Offset Null Techniques Increase Op Amp Drift, EDN Magazine.
