AD7266 is a dual, 12-bit, high speed, low power, successive approximation ADC that operates from 2.7 V to 5.25 V with power consumption of 9 mW to 27 mW. It features an on-chip reference, high accuracy, multiple package options, and more.
The AD7266 is a dual, 12‑bit, high‑speed, low‑power successive‑approximation ADC that operates from a single 2.7 V to 5.25 V supply. It provides three programmable analog inputs per ADC, selectable as single‑ended, pseudo‑differential, or fully differential, and features a high‑speed serial interface (SPI/QSPI/MICROWIRE). The device includes an on‑chip 2.5 V reference and supports both standard and 2×Vref input ranges.
The datasheet details electrical specifications, pin configurations, timing parameters, absolute maximum ratings, and recommended PCB layout guidelines. Ordering information for LFCSP and TQFP packages, as well as evaluation board options, are also provided.
