National Semiconductor ADC084S021 Datasheet
The ADC084S021 is a low‑power, four‑channel CMOS 8‑bit analog‑to‑digital converter with a serial interface. It operates from a single supply voltage of +2.7 V to +5.25 V and supports sample rates from 50 kSPS up to 200 kSPS. The device is offered in a 10‑lead MSOP package and is rated for industrial temperature operation from –40 °C to +85 °C.
Key features include variable power management, four input channels, typical power consumption of 1.6 mW at 3 V and 5.8 mW at 5 V, and performance specifications such as DNL +0.04 LSB, INL +0.04 LSB, and SNR ≈ 49.6 dB. The document contains ordering information, pin descriptions, absolute maximum ratings, electrical characteristics, timing diagrams, and application notes.
