The AD7760 is a 2.5 MSPS, 24-bit, 100 dB Sigma-Delta ADC with an on-chip buffer. It features a dynamic range of 120 dB and a signal-to-noise ratio of 112 dB at an output data rate of 78 kHz. The ADC is suitable for applications such as data acquisition systems, vibration analysis, and instrumentation.
The AD7760 is a 24‑bit sigma‑delta analog‑to‑digital converter that delivers high dynamic range and low noise performance. It offers up to 2.5 MSPS output data rate with programmable oversampling and an on‑chip differential amplifier for signal buffering.
The document includes functional block diagrams, pin descriptions, timing specifications, absolute maximum ratings, layout recommendations, and ordering information for the 64‑lead TQFP exposed‑pad package. It is intended for designers of high‑speed data‑acquisition systems and instrumentation.
