7.4.1 Open-Loop and Closed-Loop Operation

As a result of the very-high, open-loop dc gain of the ALM2403-Q1, the device functions as a comparator in open loop for most applications. A majority of electrical characteristics are verified in negative feedback, closed-loop configurations. Certain dc electrical characteristics, like offset, may have a higher drift across temperature and lifetime when continuously operated in open loop over the lifetime of the device.
