ON Semiconductor – NCS333: 10μV Offset, Low Power, Zero Drift Operational Amplifier

OnSemi_February2015_pg4aOnSemi-logo
The new NCS333 zero drift precision amplifier from ON Semiconductor delivers premium analog performance for front end amplifier circuits and power management designs.

  • System Efficiency: 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.
  • Precision Sensing: High DC precision parameters such as 10μV max input offset voltage and 30nV/°C (typ) offset temperature drift makes these amplifiers the ideal choice for low side current sensing and voltage differential measurement on front end sensor functions.
  • Temperature Drift: The very small voltage variation across temperature coupled with the close to zero offset 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 low product maintenance.
