Product Summary

The AD8628AUJZ is a wide bandwidth auto-zero amplifier featuring rail-to-rail input and output swings and low noise. Operation is fully specified from 2.7 V to 5 V single supply (±1.35 V to ±2.5 V dual supply). The AD8628AUJZ provides benefits previously found only in expensive auto-zeroing or chopper-stabilized amplifiers. Using Analog Devices’ new topology, these zero-drift amplifiers combine low cost with high accuracy and low noise. The applications of the AD8628AUJZ include Automotive sensors, Pressure and position sensors, Strain gage amplifiers, Medical instrumentation, Thermocouple amplifiers, Precision current sensing, Photodiode amplifier.
