The AD7626 is a 16-bit, 10 MSPS, charge redistribution

successive approximation register (SAR) based architecture

analog-to-digital converter (ADC). SAR architecture allows

unmatched performance both in noise (91.5 dB SNR) and in

linearity ( 0.ꢀ5 ꢁSB INꢁ). The AD7626 contains a high speed,

16-bit sampling ADC, an internal conversion clock, and an

internal buffered reference. On the CNV edge, it samples the

voltage difference between the IN+ and IN− pins. The voltages

on these pins swing in opposite phase between 0 V and REF.

The ꢀ.096 V reference voltage, REF, can be generated internally

or applied externally.

APPLICATIONS

Digital imaging systems

Digital X-ray

Digital MRI

All converted results are available on a single ꢁVDS self-clocked

or echoed-clock serial interface, reducing external hardware

connections.

CCD and IR cameras

High speed data acquisition

High dynamic range telecommunications receivers

Spectrum analysis

The AD7626 is housed in a 32-lead, 5 mm × 5 mm ꢁFCSP with

operation specified from −ꢀ0°C to +85°C.
