DESCRIPTION
The AFE0064 is a 64 channel analog front end
designed to suit the requirements of flat panel
detector based digital X-ray systems.
The device includes 64 integrators, a PGA for full
scale charge level selection, correlated double
sampler, 64 as to 2 multiplexer, and two differential
output drivers.
Hardware selectable Integration polarity allows
integration of a positive or negative charge and provides more flexibility in system design. In addition,
the device features TFT (Thin Film Transistor from
Flat Panel Detector) charge injection compensation.
This feature helps maximize the usable signal charge
range of the device.
The nap feature enables substantial power saving. This is especially useful for power saving during long
X-ray exposure periods.
The AFE0064 is available in a 128 pin TQFP
package.
