The AD7452 is a 12-bit, high speed, low power, successive approximation (SAR) analog-to-digital converter that features a fully differential analog input
The AD7452 is a 12‑bit successive‑approximation ADC that offers fully differential analog inputs and a selectable 3 V or 5 V supply. It delivers up to 555 kSPS conversion rate while consuming only a few milliwatts of power (3.3 mW at 3 V, 7.25 mW at 5 V). The device includes a low‑noise, wide‑bandwidth track‑and‑hold amplifier and supports multiple serial interfaces such as SPI, QSPI, Microwire, and DSP‑compatible modes.
Typical applications include transducer interfaces, battery‑powered systems, data‑acquisition equipment, and portable instrumentation. The datasheet provides detailed specifications, timing diagrams, pin configuration, absolute maximum ratings, and terminology definitions to aid designers in integrating the AD7452 into their designs.
