The AFE1256 is a 256-channel, analog front-end (AFE) designed to suit the requirements of
flat-panel detectors (FPDs) based on 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 16-bit,
successive-approximation register (SAR) analog-to-digital converters (ADCs) onboard. Serial data
from the ADCs are available in SPI™ format.
Hardware-selectable integration polarity allows for the integration of positive or
negative charge and provides more flexibility in system design. The Nap feature enables substantial
power saving. This power savings is especially useful in battery-powered systems.
The device is available as a 22-mm × 5-mm gold-bumped
die and a 38-mm × 28-mm, COF-314 TDS package in
singulated forms.
