Analog Devices AD7457 12‑Bit ADC Datasheet
The AD7457 is a 12‑bit successive‑approximation ADC that operates from a single 2.7 V to 5.25 V supply. It offers pseudo‑differential inputs, a high‑speed SPI/QSPI/MICROWIRE serial interface, and no pipeline delays, making it suitable for battery‑powered and portable instrumentation.
Key features include low power consumption (0.9 mW at 3 V, 100 kSPS), flexible clock management, automatic power‑down, and a typical ENOB greater than 10 bits with a 500 mV reference. The device is supplied in an 8‑lead SOT‑23 package.
