Integrated analog front-end designed to simplify sensor interfaces

03-08-2015 | Digikey | Semiconductors

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.
