3 Description
The AFE2256 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 with dual banking, and
256:4 analog multiplexers.
The device also features four 16-bit successiveapproximation
register (SAR) analog-to-digital
converters (ADCs). Serial data from the ADCs are
available in low-voltage differential signaling (LVDS)
format.
The nap and power-down modes enable substantial
power savings, and are especially useful in batterypowered
systems.
