AS585xB General Description
1 General Description
AS585xB is a family (AS5850B, AS5851B and AS5852B) of 16-bit, 256-channel low-noise charge-todigital converters designed for digital X-Ray systems.
It enables a wide range of applications for digital X-ray including static and dynamic Flat Panel Detectors (FPDs) used in radiographic imaging, digital mammography, fluoroscopy, surgery and industrial non-destructive testing.
Each of the devices consists of 256 analog Charge Sensitive Amplifiers (CSA) with a programmable full-scale range, a Correlated Double Sampler (CDS) for offset compensation with programmable time constant and 128 multiplexed Analog-to-Digital Converters (ADC) for the digital readout of each pixel.
The device can be configured for electrons and holes polarity and includes a voltage reference and a temperature sensor.
Built-in diagnostic modes enable error detection in the signal chain.
The converted channels are output on a single LVDS interface with a data rate up to 320 Mbps for optimized line time.
The serial SPI interface allows the configuration of the analog frontend including timing and different power modes for low stand-by power consumptions and fast startup times.
The AS5850 device is a high-speed design optimized for line times down to 20 µs for dynamic fl...
