AD7621 is a 16-bit, 2 LSB INL, 3 MSPS PulSAR® ADC.
The AD7621 is a 16‑bit, charge‑redistribution SAR analog‑to‑digital converter capable of up to 3 MSPS throughput in wideband warp mode. It operates from a single 2.5 V supply, includes an internal 2.048 V reference, and offers both parallel and serial (SPI/QSPI/MICROWIRE/DSP‑compatible) interfaces.
The device features a differential input range of ±VREF (up to 2.5 V), typical power dissipation of 65 mW at 3 MSPS, and operates from –40 °C to +85 °C. Detailed pin configurations, timing specifications, and application guidelines are provided for system integration.
