AD7851 is a high-precision 14-bit ADC with a single 5 V power supply, providing a 333kSPS throughput rate, self-calibration and system calibration, and a 24-lead PDIP, SOIC and SSOP package.
The AD7851 is a high‑speed 14‑bit analog‑to‑digital converter offering up to 333 kSPS throughput (A‑grade) or 285 kSPS (K‑grade). It operates from a single 5 V supply, provides pseudo‑differential inputs with two voltage ranges, and includes system and self‑calibration on power‑up.
The device is available in 24‑lead PDIP, SOIC, and SSOP packages and features low power consumption (60 mW typical, 5 µW in power‑down). Detailed specifications cover dynamic performance, DC accuracy, timing, absolute maximum ratings, and pin‑out information, making it suitable for speech processing, spectrum analysis, instrumentation, and high‑speed modems.
