National Semiconductor ADC124S021 Datasheet
The ADC124S021 is a low‑power, four‑channel CMOS 12‑bit analog‑to‑digital converter with a high‑speed serial interface. It operates from a single supply of +2.7 V to +5.25 V and offers a sample‑rate range of 50 kSPS to 200 kSPS. The device includes variable power‑management features, a built‑in track‑and‑hold circuit, and is packaged in a 10‑lead MSOP.
Key specifications include typical power consumption of 2.2 mW at 3 V and 7.9 mW at 5 V, DNL of +0.4/‑0.2 LSB, SNR of 72 dB, and operation over –40 °C to +85 °C. Ordering information, pin descriptions, absolute maximum ratings, timing diagrams, and application notes are provided for designers.
