The AD7671 is a 16-bit, 1 MSPS CMOS ADC with high precision and low power consumption.
The AD7671 is a 16‑bit, 1 MSPS charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It offers high‑speed throughput (1 MSPS in Warp mode, 800 kSPS in Normal mode), low power consumption, and a maximum integral nonlinearity of 2.5 LSB with no missing codes. The device supports bipolar and unipolar input ranges and provides both 8‑/16‑bit parallel and 2‑wire serial interfaces compatible with 3 V or 5 V logic.
The datasheet includes detailed specifications, pin configurations, timing diagrams, ordering information, and safety notes such as ESD sensitivity. It also provides definitions of key performance metrics like INL, DNL, SNR, THD, and SFDR.
