ANALOG DEVICES ADA4351-2ACPZ-R7 Programmable/Variable Amplifier, Programmable Gain, 2 Channels, 2 Amplifiers, 8.5 MHz, -40 °C

ADA4351-2ACPZ-R7 is a compact, monolithic, dual-channel, precision, programmable gain transimpedance amplifier (PGTIA). It is a breakthrough solution for precisely measuring small currents over a wide dynamic range. It enables users to perform one calibration of the end equipment at room temperature, thereby saving test time and cost. This device integrates two low-off leakage current switches per channel, and the gain is programmable using two user-selectable external resistors to provide a flexible, fully functional compact PGTIA solution. It is used in applications such as precision current to voltage (I to V) conversion, programmable gain TIAs, photodetector interface and amplification, optical networking equipment, optical power measurement, instrumentation spectroscopy and chromatography, precision data acquisition systems (DAQ).
