The AD7664 is a 16-bit, 570kSPS PulsAR® unipolar CMOS ADC
The AD7664 is a 16‑bit, 570 kSPS charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It offers both parallel and 2‑wire serial interfaces compatible with 3 V or 5 V logic and includes internal error‑correction circuitry.
Key features include a maximum throughput of 570 kSPS in Warp mode, a maximum integral non‑linearity of +2.5 LSB, single‑supply power dissipation of 115 mW (down to 21 µW at 100 SPS in Impulse mode), and a 0 V to 2.5 V unipolar input range. The device is supplied in 48‑lead LQFP and LFCSP packages and is rated from –40 °C to +85 °C.
