For the lowest offset and drift performance, chopper-stabilized (auto-zero) amplifiers may be the only solution. The best bipolar amplifiers offer offset voltages of 25 μV and 0.1 μV/ºC drift. Offset voltages less than 5 μV with practically no measurable offset drift are obtainable with choppers, albeit with some penalties.
