AD7626:  16-Bit, 10MSPS PulSAR Differential ADC

Product 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 (92 dB SNR) and in linearity (1 LSB). 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.
