It has ultra-low offset, bias and bias current. The AD8574-EP is a quad amplifier with rail-to-rail input and output swings. It is guaranteed to operate from a single supply from 2.7 V to 5 V.
The AD8574-EP provides benefits previously only available in expensive auto-reset or chopper stabilized amplifiers. Using a patented spread spectrum, auto-zero technique, the AD8574 eliminates intermodulation effects caused by the interaction of the signal frequency and the subsequent cutoff function in ac applications.
