AD8488 - 128-Channel Digital X-Ray Analog Front End

Datasheet Summary

Description

The AD8488 is a 128-channel, analog front end (AFE) designed for use in high performance digital X-ray systems.

The analog channels consist of an integrator followed by a gain selectable single-ended to low impedance differential output.

Features

  • 128 integrator channels Correlated double sample error correction (CDS) Corrects for VOS and LF noise Power consumption per channel Normal: 11 mW Low power: 4 mW Low input leakage current:.
  • 1.5 pA typical Low input referred noise (QNI): 993 e.
  • rms typical Linearity error: 0.03% typical Compact 17 mm × 17 mm BGA Selectable filter time constants 4 selectable input charge ranges 10 selectable gain ranges.
