General Description
The MAX420, 421, 422, and 423 are a series of ±15V CMOS chopper-stabilized amplifiers, designed for high accuracy amplification, signal conditioning and instrumentation applications. these devices offer input offset and drift specification superior to previous "precision" bipolar amplifiers and monolithic choppers. The maximum offset is 5.0 μV while the guaranteed drift limit is 0.05μV/°C.

Applications
   Precision Amplifiers
   Signal Conditioning for:
      Thermocouples
      Strain Gauges, Load Cells
      Thermistors, Bridges
   High Accuracy Data Acquistion
   D.C. Stabilization of Amplifiers and Systems
