AD7626 is a 16-bit, 10 MSPS, PulSAR differential ADC chip from Analog Devices, which has 16-bit no missing codes, 91.5 dB SNR, low power consumption and other features.
The AD7626 is a 16‑bit, 10 MSPS charge‑redistribution successive‑approximation ADC offered by Analog Devices. It features a differential input range of ±4.096 V, an internal 4.096 V reference (or external reference options), and a serial LVDS interface that can operate in self‑clocked or echoed‑clock modes.
Housed in a 32‑lead 5 mm × 5 mm LFCSP package, the device operates from –40 °C to +85 °C and consumes as little as 88 mW when idle. Detailed specifications, pin descriptions, timing diagrams, and absolute maximum ratings are provided for designers.
