ADS7822UB

The ADS7822UB is a Texas Instruments 12‑bit, two‑channel, single‑supply analog‑to‑digital converter (SAR type) with a serial interface. It multiplexes two analog inputs into a 12‑bit conversion, using an SPI/MICROWIRE‑style interface for MCU communication. It is designed for low power, modest-speed data acquisition and is suitable for portable and embedded systems.
Key points:
- 12-bit resolution, two input channels (multiplexed)
- SAR architecture for fast, precise conversions
- Single-supply operation (typical 2.7–5.25 V)
- Serial digital output: SPI/MICROWIRE‑compatible
- Low power, with internal sample-and-hold
- UB suffix indicates packaging variant (connectivity/performance similar; check datasheet for exact package)
Common uses: sensor interfacing, data acquisition, control systems in embedded projects. For exact electrical specs (sampling rate, input range, timing), consult the TI ADS7822UB datasheet.
