... Data acquisition Integrators Input buffering GENERAL DESCRIPTION The ADA4062-2 and ADA4062-4 are dual and quad JFET-input amplifiers with industry-leading performance. They offer lower power, offset voltage, drift, and ultralow bias current. The ADA4062-2 B grade (SOIC package) features a typical low offset voltage of 0.5 mV, an offset drift of 5 μV/°C, and a bias current ...

... ADA4062-2/ADA4062-4 PHASE REVERSAL Phase reversal occurs in some amplifiers when the input common- mode voltage range is exceeded. When the voltage driving the input to these amplifiers exceeds the maximum input common- mode voltage range, the output of the amplifiers changes polarity. Most JFET input amplifiers have phase reversal if either input exceeds the input common-mode range ...
