The bias current, drift, and offset of this family of amplifiers are extremely low. Rail-to-rail input and output swings are a feature of the single, dual, and quad amplifiers designated AD8571, AD8572, and AD85741, respectively. All are guaranteed to function with a single supply between 2.7 V and 5 V.
The AD8571, AD8572, and AD8574 offer advantages that were previously only available in pricey auto-zeroing or chopper-stabilized amplifiers. These zerodrift amplifiers combine low cost and great accuracy using Analog Devices, Inc.'s architecture. (External capacitors are not necessary.) The AD8571/AD8572/AD8574 reduce the intermodulation effects caused by interaction of the chopping function with the signal frequency in ac applications by using a spread-spectrum, auto-zero approach.
