AD7763 is a 24-bit, 625 kSPS, 109 dB Σ-Δ ADC with on-chip buffers and serial interface
The AD7763 is a high‑performance 24‑bit analog‑to‑digital converter offering up to 625 kSPS output data rate, 120 dB dynamic range at 78 kHz and 107 dB SNR at 625 kHz. It features on‑chip differential amplifiers, programmable FIR filtering, over‑range detection, and low‑power modes, making it suitable for compact data‑acquisition designs.
Typical applications include high‑speed data acquisition, vibration monitoring, and instrumentation. The device is supplied in a 64‑lead TQFP exposed‑paddle package and operates over an industrial temperature range of –40 °C to +85 °C.
