ADA4530 Electrometer-Grade Amplifier

This design is used to evaluate the ADA4530 femtoampere (10^-15 A) level input bias current operational amplifier, suitable to be use as an electrometer. It has an operating voltage range of 4.5V to 16V enabling it to operate in conventional 5V and 10V single supply systems as well as ±2.5V and ±5V dual supply systems. The board also offers low offset voltage, low offset drift, and low voltage and current noise needed for the types of applications that require such low leakages. To maximize the dynamic range of the system, it has a rail-to-rail output stage that can typically drive to within 30mV of the supply rails under a 10kΩ load. Read more
