The AD7650 is a 16-bit, 570 kSPS, charge redistribution SAR, analog-to-digital converter. It offers excellent performance in terms of low power consumption, low cost and high accuracy.
The AD7650 is a 16‑bit, 570 kSPS SAR analog‑to‑digital converter that operates from a single 5 V supply. It offers high‑speed sampling in Warp mode, a normal 500 kSPS mode, and a low‑power Impulse mode, with power dissipation scaling with throughput.
The device is available in a 48‑lead LQFP or a 48‑lead chip‑scale package and supports both parallel and 2‑wire serial interfaces compatible with 3 V or 5 V logic. It is suited for data acquisition, instrumentation, DSP, and spectrum analysis applications.
