The ADA4661-2 and ADA4666-2 feature high precision (low offset voltage and low
input bias current), rail-to-rail input and output, and low power in
mid-voltage supply range (single supply 3V to 18V or dual supply ±1.5V to ±9V).
Besides that, the unique design architecture of the ADA4661-2 and ADA4666-2
allows them to have excellent power supply rejection and common mode rejection
when operating in the common mode voltage of –VSY+1.5V and +VSY-1.5V.
