AFE0256 Description
The AFE0256 is a 256-channel analog front-end (AFE) designed to suit the requirements of flat-panel detector (FPD)-based digital x-ray systems. The device includes 256 integrators, a programmable gain amplifier (PGA) for full-scale charge level selection, a correlated double sampler (CDS) with dual banking, 256:4 analog multiplexers, and four differential output drivers.
