The chopper-stabilized architecture eliminates 1\/f noise and maintains ultra-low offset voltage over time and temperature.","working_principle":"The zero-drift architecture uses an auto-zeroing technique. The amplifier continuously measures and cancels its own offset voltage. A chopper circuit alternately connects the input to the signal and to a short-circuit, allowing the offset to be sampled and subtracted. This eliminates both initial offset and drift, resulting in no 1\/f noise corner.","pin_description":"
