ADI ADA4530 Femtoampere Input Bias Current Electrometer Amplifier
The ADA4530-1 is a femtoampere (10−15 A) level input bias
current operational amplifier suitable for use as an electrometer
that also includes an integrated guard buffer. It has an operating
voltage range of 4.5 V to 16 V, enabling it to operate in conventional 5 V and 10 V single supply systems as well as ±2.5 V and
±5 V dual supply systems.
