AD7762 is a 625 kSPS, 24-Bit, 109 dB Σ−Δ ADC product from Analog Devices. It has high dynamic range, high precision and low power consumption. It is suitable for data acquisition systems, vibration analysis and other applications.
The AD7762 is a high‑performance 24‑bit analog‑to‑digital converter designed for data‑acquisition systems, vibration analysis and instrumentation. It features a fully differential modulator, on‑chip differential amplifier, programmable oversampling, and a low‑pass FIR filter with user‑programmable coefficients.
The device is supplied in a 64‑lead TQFP package and operates over an industrial temperature range (‑40 °C to +85 °C). It supports synchronization of multiple converters via a SYNC pin and includes low‑power and standby modes for power‑sensitive applications.
