Product features

The AS5852B is a 16-bit, 256-channel low-noise charge-to-digital converter designed for use in digital X-ray systems. The high degree of programmability enables system performance optimization in a wide range of applications. The combination of fast speed, low noise and low power consumption maximizes the image quality and minimizes patient dose, exposure whilst improving the time to market.
Each channel front-end consists of a charge sensitive amplifier (CSA) and a correlated double sampler (CDS), that removes offset and flicker noise from the signal, which is then converted to digital. A fast and reliable LVDS interface transmits the output digital data off-chip. Built-in diagnostic functionalities enable to locate the source of errors in the signal chain from the detector to the data acquisition system. Voltage references and a temperature sensor are included on the chip. An SPI interface allows easy programming of the device parameters.
A line time of 80 μs requires as little as 1.1 mW per channel. Additionally, it is possible to add together the charges in pairs of adjacent channels; with this binning, the fastest achievable line time is 40 μs.
