The AD7492 is a 12-bit high-speed, low-power successive-approximation ADC. The device operates from a single 2.7 V to 5.25 V power supply and supports throughput rates up to 1.25 MSPS. The AD7492 contains a low-noise, wide bandwidth 2.5 V internal reference and on-chip clock oscillator. It also features flexible power/throughput rate management and no pipeline delays. The AD7492 is ideal for a variety of high-precision measurement applications.
The AD7492 and AD7492‑5 are 12‑bit high‑speed, low‑power parallel ADCs that operate from a single 2.7 V to 5.25 V supply and offer throughput rates up to 1.25 MSPS. They feature an internal 2.5 V reference, on‑chip clock oscillator, and flexible power‑throughput management with partial and full sleep modes.
The document includes functional block diagrams, detailed pin descriptions, absolute maximum ratings, timing specifications, ordering information, and a full set of electrical specifications such as resolution, SNR, conversion time, and power consumption for both normal and sleep modes.
