AS5900: 128-CHANNEL LOW NOISE CURRENT-TO-DIGITAL CONVERTER

High Performance CT Detector Interface Solution

The ams AS5900 is a low noise, 26-bit, 128-Channel Current-to-Digital, Analog-to-Digital (ADC) Converter. This new high performance sensor interface solution enables medical, industrial and security CT scanners to render sharper and more detailed images. 

 The AS5900 converter enables the readout of photodiodes with highest sensitivity. High resolution CT imaging can be achieved up to 26-bits resolution. Its 128-low-noise and high linear converter channels provide an increased gray scale, improved contrast and reduce artifacts of 3D CT images. The low power consumption of 1mW per channel reduces self-heating effects and the overall power consumption of the system. An integrated temperature sensor allows the calibration of temperature drifts of the X-ray detector modules.
