Overview
Data Sheet 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 APPLICATION High performance digital X-ray systems Medical X-ray Security (baggage scanner) systems 128-Channel Digital X-Ray Analog Front End AD8488 GENERAL 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.
The analog channel converts the charge acquired by X-ray or photodiode detectors to a voltage.
The channels are composed of CMOS transistors, using typical high i...
