Analog Devices AD7661 16‑Bit 100 kSPS PulSAR® Unipolar ADC Datasheet
The AD7661 is a 16‑bit charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It includes an internal 2.5 V reference, error‑correction circuitry, and offers both parallel and 2‑wire serial interfaces compatible with 3 V and 5 V logic.
The device provides 100 kSPS throughput, ±2.5 LSB INL, 88 dB minimum SNR, and –96 dB maximum THD. It is available in 48‑lead LQFP and LFCSP packages and is rated for –40 °C to +85 °C operation. Typical applications include data acquisition, medical instruments, signal processing, and battery‑powered systems.
