Integrated analog front-end designed to simplify sensor interfaces

Analog Devices' ADA4350 is now available from Digi-Key. The device is an analog front end for photodetectors or other sensors whose output produces a current proportional to the sensed parameter or voltage input applications where the system requires the user to select between very precise gain levels to maximize the dynamic range. The ADA4350 integrates a FET input amplifier, a switching network, and an ADC driver with all functions controllable via a serial peripheral interface (SPI) or parallel control logic into a single IC. The FET input amplifier has very low voltage noise and current noise, making it ideal for working with a wide range of photodetectors, sensors, or precision data-acquisition systems, says the company.
