AFE2256GRTDX

Analog Front End (AFE) Overview

The AFE2256GRTDX is a 256-channel analog front-end designed for digital X-ray flat-panel detectors. It integrates 256 integrators, a programmable gain amplifier, correlated double samplers with dual banking, and 256:4 analog multiplexers. The device features four 16-bit successive-approximation register (SAR) ADCs with serial LVDS output. Key performance metrics include 750 electrons RMS noise within a 1.2-pC input charge range, integral nonlinearity of ±2 LSB, and scan times ranging from less than 20 µs to 204.8 µs. Power supply requirements are AVDD1 at 1.85 V and AVDD2 at 3.3 V.

Analog Front End (AFE) Procurement Notes

Verify the specific package variant associated with the GRTDX suffix against the official TI orderable part list. Confirm that the selected package meets the required operating temperature range and moisture sensitivity level for the intended application environment.

Analog Front End (AFE) Selection Notes

Select this component for high-channel-count X-ray imaging systems requiring low noise and fast readout speeds. Ensure the system design accommodates the custom Chip-On-Film (COF) packaging constraints and utilizes the specified 1.85 V and 3.3 V power rails.

Analog Front End (AFE) Part Context

The AFE2256 belongs to Texas Instruments' family of analog front-ends specifically engineered for medical imaging applications. It addresses the need for high integration in flat-panel detector modules by consolidating signal conditioning, amplification, and digitization into a single device.
