The AD7980 is a 16-bit, 1 MSPS PulSAR ADC with features such as low power dissipation, high accuracy, and single-supply operation. It can be widely used in battery-powered equipment, communications, ATE, data acquisition, and medical instrument applications.
The AD7980 is a 16‑bit successive‑approximation ADC that operates from a single 2.5 V supply and supports 1 MSPS conversion rates. It offers a serial SPI‑compatible interface, optional daisy‑chain capability, and a wide input voltage range from 0 V to the external reference.
The device is offered in 10‑lead MSOP and QFN (LFCSP) packages, operates from –40 °C to +125 °C, and is suited for battery‑powered equipment, communications, ATE, data acquisition, and medical instruments.
