ON Semiconductor NCxx333 Zero Drift Operational Amplifiers with 10 uV Offset

The high analog performance offered by the zero-drift architecture enhances motor control feedback-loop accuracy and power supply control loop contributing to higher system efficiency. The high DC precision parameters of input offset voltage and offset temperature drift makes these amplifiers the ideal choice for low side current sensing and voltage differential measurement on front end sensor functions. The very small voltage variation across temperature coupled with the close to zero offsets ensures the stability of the system operation facing wide temperature exposure without using complex and expensive software calibration algorithms resulting in a more manageable design and product maintenance.
