The AD7273/AD7274 are 10-/12-bit high speed, low power, successive approximation ADCs, respectively. The parts operate from a single 2.35 V to 3.6 V power supply and feature throughput rates of up to 3 MSPS.
The AD7273 and AD7274 are 10‑/12‑bit successive‑approximation ADCs that operate from a single 2.35 V to 3.6 V supply. They deliver up to 3 MSPS throughput while consuming very little power, making them suitable for high‑speed, low‑power applications.
The devices feature a wide‑bandtrack‑and‑hold amplifier, flexible SPI/QSPI/MICROWIRE/DSP‑compatible serial interfaces, and an external reference input that can be driven up to the supply voltage. Detailed specifications, timing diagrams, and application hints are provided throughout the document.
