ams AS5911
The AS5911 is an ultra-low noise, 256-channel low power current to digital converter that enables the readout of photodiodes of a CT detector with highest sensitivity. The output currents of 256 photodiodes are converted simultaneously into digital without any dead time resulting in no charge loss on the inputs. The AS5911 combines current-to-voltage integration and A/D conversion for 256channels in one device.| Part No. | AS5911 |

GENERAL DESCRIPTION
1GENERAL DESCRIPTION
The ADC architecture with its low-noise integrators, coarse quantizer, sampleand-hold and fine quantizer guarantee lowest input related noise of maximum 0.29 fC (low noise mode) at an input current range of 0.5 µA. The input current range of the ADC is selectable between 0.5 µA and 1 µA. The AS5911 supports two supply concepts: a single analog and true ground supply, in both modes the photodiodes are zero biased for ultra-low dark current of the photodiode.
