The AD74531 is a 12-bit, high speed, low power, successive approximation (SAR) analog-to-digital converter that features a pseudo differential analog input. This part operates from a single 2.7 V to 5.25 V power supply.
The AD7453 is a 12‑bit successive‑approximation ADC offering pseudo‑differential inputs, up to 555 kSPS throughput and operation from a single 2.7 V to 5.25 V supply. It features low power consumption (3.3 mW at 3 V, 7.25 mW at 5 V) and a high‑speed serial interface compatible with SPI, QSPI, Microwire and DSP protocols.
The device is supplied in an 8‑lead SOT‑23 package and includes detailed specifications, timing diagrams, pin descriptions, and application hints for PCB layout and grounding. Ordering information and evaluation board options are also provided.
