The AD7674 is a 18-bit, 2.5 LSB INL, 800 kSPS SAR ADC with 18-bit resolution, no missing codes, no pipeline delay (SAR architecture) and 5 V input range.
The AD7674 is an 18‑bit, charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It offers high resolution, fast throughput (up to 800 kSPS in warp mode) and both serial and parallel interfaces compatible with 3 V and 5 V logic.
The device is supplied in 48‑lead LQFP or LFCSP packages and is specified for operation from –40 °C to +85 °C. Detailed specifications cover resolution, input range, power dissipation, timing, absolute maximum ratings, and pin functions.
