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.
