The zero-drift architecture uses auto-zeroing (chopper stabilization): the input offset voltage is continuously measured and cancelled every clock cycle (typically 8kHz internal chopping frequency). This results in a maximum offset voltage of 10uV over temperature (-40C to +125C) and virtually zero drift (0.05uV\/C). The chopper technique also eliminates 1\/f flicker noise, giving flat noise density of 55nV\/sqrt(Hz) from DC to 400Hz. The input bias current is only 70pA (typical), suitable for high-impedance sensors like pH probes and photodiodes. The rail-to-rail output swings to within 50mV of the rails with a 10k-ohm load. The input common-mode range extends 100mV beyond the rails (RR I\/O), a key advantage for single-supply designs. The auto-zeroing process creates small charge injection glitches at the chopping frequency, appearing as 55nV\/sqrt(Hz) noise peaks at 8kHz and harmonics. For DC and low-frequency applications, these are negligible; for audio applications, a simple RC filter at 10kHz attenuates them below the noise floor.","pin_description":"
