16-Bit, 10 MSPS, PulSAR Differential ADC
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 low voltage differential signaling (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.

The EVAL-AD7626FMCZ is a fully featured evaluation kit for the AD7626. This board operates in conjunction with the System Development Platform board, EVAL-SDP-CH1Z. When operated with the System Development Platform board, software is provided enabling the user to perform detailed analysis of the ADC's performance. This software has an accompanying user guide describing the operation and set up of the evaluation board when operated with the System Development Platform board.
