Analog Front End (AFE) datasheet and documents for AFE0256GBTD

AFE0256GBTD

Analog Front End (AFE) Overview

The AFE0256GBTD is a 256-channel analog front-end (AFE) designed for flat-panel digital X-ray detectors. It integrates 256 integrators, a programmable gain amplifier (PGA), and a correlated double sampler (CDS). The device features four on-chip 14-bit successive-approximation register (SAR) ADCs with an internal reference voltage of 2.5 V. Key electrical parameters include a noise level of 758 electron RMS with a 28-pF sensor capacitor in the 1.2-pC range, integral nonlinearity of ±1.25 LSB, and selectable full-scale charge ranges from 0.15 pC to 9.6 pC. It supports scan times as low as 26 µs in 2x binning mode.

Analog Front End (AFE) Feature Summary

256 integrated channels with on-chip 14-bit SAR ADCs
Low noise performance: 758 eRMS with 28-pF sensor capacitor
Hardware-selectable integration polarity for electron or hole detection
Pipelined integration and read architecture allows data read during integration

Analog Front End (AFE) Applications

Flat-panel X-ray detectors
Digital radiography systems
Computed tomography (CT) scanners

Analog Front End (AFE) Procurement Notes

Verify the NRND status before design implementation. Confirm package compatibility for Tape Carrier Package (TCP) or Chip-on-Film (COF) assembly. Check moisture sensitivity level (Level-1) handling requirements. Ensure supply availability aligns with production timelines.

Analog Front End (AFE) Selection Notes

Select this component for high-density X-ray imaging arrays requiring integrated signal processing. Evaluate power consumption specifications (2.9 mW/channel with ADC) against system thermal constraints. Verify interface compatibility with external controllers via SPI format.

Analog Front End (AFE) Part Context

The AFE0256GBTD is a singulated die variant of the AFE0256 family. It is packaged in a 22-mm × 5-mm gold-bump configuration suitable for direct bonding to flexible substrates. This form factor distinguishes it from standard leaded or QFN packages used in other TI AFE series.
