The AS5912 is an ultra-low noise, 512-channel low power current to digital converter that enables the readout of photodiodes of a CT detector. The ADC architecture with its low-noise integrators, coarse quantizer, sample and hold and fine quantizer guarantee lowest input related noise down to 0.29 fC. The power dissipation is below 1.25 mW per channel for reduced self-heating of the CT detector.

特性

  • 512-channel in 15 x 23 mm² FBGA package
  • Ultra-low noise of 0.29 fC at 0.5 μA
  • Lowest power dissipation of 1.25 mW/channel
  • Adjustable integration time down to 51 μs
  • Zero biased PD for ultra-low dark currents
  • Linearity of ±0.080% of reading
  • Automatic Calibration Routines

产品优势

  • No external components required. Integrated capacitors for supply and reference decoupling
  • No charge loss. Continuous charge integration due to zero dead time of ADC architecture
  • Selectable full-scale range of 0.5 μA in low range and 1 μA in high range
  • Adjustable full-scale range, integration time and power consumption via SPI interface as well as adjustable output modes via LVDS
  • Selectable power supply concept between dual ±1.5 V analog supply (true ground concept) or single +3.0 V analog supply
  • On-chip LDOs, voltage references and temperature sensor
  • Built-in diagnostic modes for testing full detector signal chain
