The AD7856 is a high-speed, low-power, 14-bit ADC that operates from a single 5 V power supply. The ADC powers up with a set of default conditions at which time it can be operated.
The AD7856 is a 14‑bit, 285 kSPS analog‑to‑digital converter that operates from a single 5 V supply. It offers eight single‑ended or four pseudo‑differential input channels, low power consumption (≈60 mW typical) and automatic power‑down after conversion.
The document provides detailed specifications, timing diagrams, pin descriptions, absolute maximum ratings, calibration procedures and interface options (8051/SPI/QSPI/µP compatible). It also includes ordering information and application hints for battery‑powered and high‑speed systems.
