Not by Drift Alone...

Voltage offset drift is commonly considered to be the most important factor limiting op amp accuracy at low frequencies, with drifts due to current bias and offset closely vying for second place. Recognizing (and perhaps overreacting to) the importance of low drift specifications, IC op amp manufacturers (and purveyors) have offered such popular devices as the SSS725E, the LM208A (and the BB3500E), which feature either low offset or bias current or low voltage drift. Read full article
