Dexela 23 cm x 29 cm (!) 12MP CMOS Imager

Talking about huge imagers, like one presented by Canon at ISSCC, there is even bigger CMOS sensor made by Dexela, model 2923, first announced a year and a half ago:

  • Resolution: 3888 x 3072 pixels
  • Sensitive area: 290.8 mm x 229.8 mm
  • Pixel size: 74.8 um
  • Saturation charge: 1.4 Me- in high saturation mode, 0.36 Me- in high sensitivity mode
  • Dynamic range: 70dB typ. in high saturation mode, 66dB typ. in high sensitivity mode
  • Dark current: 8000 e-/s (typical at 40C)
  • ADC resolution: 14 bits
  • Speed: 26 fps at full resolution
  • Power consumption: 45 W max (active)
  • Power down current: <150 mA

The sensor is intended for X-Ray sensing applications. Packaging of such a huge and power hungry sensor is also challenging: the package weights 5.5kg and includes two fans:
