The AD7764 is a high performance, 24-bit Σ-Δ analog-to-digital converter (ADC). It combines wide dynamic range, high resolution, low power and flexible serial interface. The AD7764 is suitable for data acquisition systems, vibration analysis and instrumentation applications.
The AD7764 is a high‑performance 24‑bit analog‑to‑digital converter offering up to 312 kSPS output data rate, selectable oversampling, and on‑chip differential amplifiers. It includes features such as an overrange alert pin, synchronization via a SYNC pin, and daisy‑chaining capability for multi‑device systems.
The device is supplied in a 28‑lead TSSOP package and operates over an industrial temperature range of –40 °C to +85 °C. Power consumption varies with mode, with typical dissipation of 300 mW in normal mode and 160 mW in low‑power mode.
