Ultrahigh Sensitivity Femtoampere Measurement Platform based on ADA4530-1

System functional diagram is a precision analog front end for measurement of current down to the femtoampere range. This industry-leading solution is ideal for chemical analyzers and laboratory grade instrument where an ultrahigh sensitivity analog front end is required for signal conditioning current output sensors such as photodiodes, photomultiplier tubes, and Faraday cups. Applications that can use this solution include mass spectrometry, chromatography, and coulometry. The data acquisition board uses an AD7172-2, 24-bit analog-to-digital-converter (ADC) and is powered from a single 9 Vdc supply
