16-Bit, 10 MSPS, 92 dB SNR, PulSAR ADC Delivers Breakthrough Performance in an LFCSP Package

The AD7626 PulSAR® ADC is a breakthrough in data conversion that delivers an unequaled combination of speed and low power. This 16-bit SAR ADC features best-in-class 15-bit ENOB and 10 MSPS throughput that is 2.5× faster than other SAR ADCs. The ability to process information at these speeds, while preserving data integrity, is a key requirement of medical imaging and data acquisition systems. Available in a compact 5 mm × 5 mm, 32-lead LFCSP, it consumes just 140 mW power—15% lower than other ADCs in its class, even at its highest sample rate. The AD7626 uses a self-clocked low voltage differential serial (LVDS) bus that provides a very low noise interface and reduces the number of external components required to address board-level noise concerns.
