GENERAL DESCRIPTION
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 (±0.45 LSB INL). 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 4.096 V reference voltage, REF, can be generated internally
or applied externally.
All converted results are available on a single LVDS self-clocked
or echoed-clock serial interface, reducing external hardware
connections.
The AD7626 is housed in a 32-lead, 5 mm × 5 mm LFCSP with
operation specified from 40°C to +85°C.
