The AS5951 is a cost-optimized sensor chip for 32-slice CT detectors that combines the photodiodes with a pixel dimension of 0.98x0.98 mm² and the readout circuit on a single CMOS chip. This sensor solution, where the photodiode array and a 128-channel ADC are side-by-side, allows the assembly of the pixel array on three adjacent edges of the device. Improved performance can be achieved due to superior dark current, noise and power consumption.

特長

  • Monolithic integration of ADC and photodiode
  • Automatic zero offset voltage calibration
  • Reference voltage and bias current generator
  • High resolution mode and low dose mode
  • Customization of pixel dimensions on request

利点

  • Ultra-low dark current of max. 1pA
  • Lowest input related noise of typ. 0.21fC
  • Fast integration time down to 200µs
  • High ADC linearity of ±600ppm including photodiode
