The AD7622 is a 2 MSPS SAR ADC with 16-bit resolution and 1.5 LSB INL.
The AD7622 is a 16‑bit, 2 MSPS charge‑redistribution SAR ADC that operates from a single 2.5 V supply. It provides fully differential analog inputs, an internal 2.048 V reference, and supports both parallel and serial digital interfaces.
Key features include high‑speed throughput (2 MSPS), low power dissipation (70 mW typical), wide input voltage range (±V REF), and extensive timing specifications for various operation modes. The device is supplied in Pb‑free 48‑lead LQFP and LFCSP packages and is rated for –40 °C to +85 °C operation.
