The ADC084S021 is a low-power, four-channel CMOS 8-bit analog-to-digital converter with a high-speed serial interface.
The ADC084S021 is a four‑channel, 8‑bit successive‑approximation CMOS analog‑to‑digital converter. It operates from a single supply (2.7 V to 5.25 V) and supports sample rates from 50 kSPS to 200 kSPS. The device is packaged in a 10‑lead MSOP and is rated for industrial temperature range –40 °C to +85 °C.
Key features include low power consumption (1.6 mW at 3 V, 5.8 mW at 5 V), built‑in power‑down mode, and compatibility with common serial interfaces such as SPI, QSPI, and Microwire. Detailed electrical characteristics, timing diagrams, and pin descriptions are provided for system integration.
