Analog Devices AD7685 Datasheet
The AD7685 is a 16‑bit charge‑redistribution successive‑approximation ADC that operates from a single supply of 2.3 V to 5.5 V. It offers a 250 kSPS conversion rate, no missing codes, and a versatile SPI‑compatible serial interface that can be daisy‑chained or include a BUSY indicator. The device is available in 10‑lead MSOP and QFN (LFCSP) packages and operates from –40 °C to +85 °C.
Typical applications include battery‑powered equipment, medical instruments, mobile communications, PDAs, data acquisition, instrumentation, and process control. The datasheet provides detailed specifications, timing diagrams, pin descriptions, absolute maximum ratings, and ordering information for various package options.
