AD7676 is a 16-bit, 500 kSPS, differential ADC from Analog Devices that offers µV level noise performance and ±0.0015% full scale INL.
The AD7676 is a 16‑bit, 500 kSPS, charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It offers high accuracy with +1 LSB INL, 94 dB typical SNR, and low power consumption (67 mW typical, 7 pW in power‑down). The device is available in 48‑lead LQFP and LFCSP packages and is suited for applications such as CT scanners, data acquisition, and medical instruments.
The datasheet includes detailed electrical specifications, timing diagrams for serial and parallel interfaces, full pin‑function tables, package dimensions, absolute maximum ratings, and an ordering guide with part numbers for each package option. Revision history and compliance information are also provided.
