The AD7091 is a 12‑bit SAR ADC offering 1 MSPS throughput with ultralow power consumption.
The AD7091 from Analog Devices is a 12‑bit successive‑approximation register analog‑to‑digital converter designed for low‑power, high‑speed applications. It operates from a single 2.09 V to 5.25 V supply and provides a full‑scale input range of 0 V to VDD.
The device features an on‑chip conversion clock, a high‑speed serial interface (SPI/QSPI/MICROWIRE), and a power‑down mode that reduces consumption to sub‑µA levels. Its 8‑lead LFCSP package (2 mm × 2 mm) makes it suitable for space‑constrained designs.
