AD7984 is a 18-bit, 1.33MSPS ADC with MSOP and QFN package, with power consumption of 10.5mW
The AD7984 is an 18‑bit successive‑approximation analog‑to‑digital converter (ADC) that operates from a single 2.5 V supply. It offers 1.33 MSPS throughput, low power dissipation (10.5 mW) and a true differential input range selectable from 2.9 V to 5.1 V.
The device features a versatile serial interface compatible with SPI, QSPI, Microwire and DSP protocols, supports daisy‑chaining of multiple converters, and includes an optional busy indicator. It is supplied in 10‑lead MSOP or 10‑lead QFN (LFCSP) packages and is rated for –40 °C to +85 °C operation.
