The AD7660 is a 16-bit, 100 kSPS PulSAR ® unipolar CMOS ADC.
The AD7660 is a 16‑bit, 100 kSPS charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It offers internal conversion clock, error‑correction circuitry, and flexible parallel or 2‑wire serial interfaces compatible with 3 V or 5 V logic.
Typical applications include data acquisition, battery‑powered systems, PCMCIA, instrumentation, scanning, and process control. The device is available in a 48‑lead LQFP (ST‑48) or a 48‑lead chip‑scale package (CP‑48).
