Instructions
AFE0064
is the 64 channel simulation The front -end design is designed with a digital X -ray system based on the detector.
The device includes 64 points, a complete PGA scale charging level selection, related dual sampling device, 64 as two multi -way relics, and two differential output drives. Hardware optional integration polarity allows integration of positive charge or negative charge, and provides greater flexibility in system design. In addition, the device is characterized by TFT (thin film transistor tablet detector) charge injection compensation. This function helps the available signal charging range of maximizing equipment.
NAP function can be greatly energy -saving. This is particularly useful for long -term power saving. X -ray exposure time.
AFE0064 can be used for 128 -pin TQFP package.
