The device operates from 2.7 V to 5.5 V single supply and features rail-to-rail output swing within 5 mV of the rails. The low 0.5 \u00b5V p-p voltage noise in the 0.1 to 10 Hz band makes it ideal for precision DC and low-frequency applications. The SOT-23-5 package enables compact PCB layouts in space-constrained designs. Dual (AD8629) and quad (AD8630) versions are also available.","working_principle":"The AD8628ARTZ-REEL7 uses Analog Devices' proprietary auto-zero (chopper-stabilized) technique to continuously correct the input offset voltage. The amplifier contains two signal paths: a main amplifier for signal processing and a nulling amplifier that continuously measures and corrects the main amplifier's offset. This auto-zeroing occurs at a high frequency (several kHz), effectively eliminating offset drift over temperature and time. The input stage uses MOSFETs to achieve very low input bias current (30 pA typical), making it suitable for high-impedance sensor interfaces. The output stage is rail-to-rail CMOS, swinging within 5 mV of either supply rail under light loads.","pin_description":"
