GENERAL DESCRIPTION
The ADA4062-2 is a dual JFET-input amplifier with industry-
leading performance. It offers lower power, offset voltage, drift
and ultralow bias current. The ADA4062-2 B grade features typical
low offset voltage of 0.5 mV, offset drift of 4 μV/°C, and bias current
of 2 pA. The ADA4062-2 is ideal for various applications, including
process control, industrial and instrumentation equipment, active
filtering, data conversion, buffering, and power control and
monitoring. With a low supply current of 165 μA per amplifier,
it is also very well suited for lower power applications. The
ADA4062-2 is specified for the extended industrial temperature
range of −40°C to +125°C and is available in lead-free SOIC and
MSOP packages.

... SY resistors, the gain of the circuit R2/R1, which is approxi- mately 100. Tighter matching of two op amps in one package the case with the ADA4062-2, offers a significant boost in performance over the 3-op-amp configuration. Overall, the circuit only requires about 330 μA of supply current. PHASE REVERSAL Phase reversal occurs in some amplifiers when the input common- mode voltage range is exceeded ...

Page 15

... Most JFET input amplifiers have phase reversal if either input exceeds the input common-mode range. For the ADA4062-2, the output does not phase reverse if one or both of the inputs exceeds the input voltage range but stays below the positive supply rail and 0.5 V above the negative supply rail. ...
