The AFE3256 is a 256-channel, analog front-end (AFE) designed to suit the requirements of flat-panel detector (FPD) based digital X-ray systems. The device includes 256 integrators, correlated double samplers (CDSs) with dual banking, and 256:2 analog multiplexers. The device also features two 16-bit successive-approximation register (SAR) analog-to-digital converters (ADCs). Serial data from the ADCs are available in low-voltage differential signaling (LVDS) format.

The device, also commonly referred to as a readout integrated circuit (ROIC), optimizes the overall system performance using features such as multiple power modes and in-system debug options.

The sleep and standby modes enable substantial power saving which is critical for battery-powered systems.
