4-Side Buttable 80-Pixel TSV ASIC with integrated PD array and ADC The AS5966 is a sensor chip for CT detectors that combines the photodiodes and the readout circuit on a single CMOS chip using through silicon vias (TSV). This sensor solution, which integrates 10 x 8 photodiodes array with pixel dimension of 1.1x1.02 mm² and an 80-channel ADC on top of each other, allowing the assembly of the pixel array on four adjacent edges of the device. It has high performance incl. ultra-low noise and power consumption.
