Microchip's MCP3221 low-power 12 bit successive approximation ADC with I2C interface is available in tiny SOT-23 package. 400 kHz fast mode enables sampling rates up to 22,3 kSa/s for higher bandwidth signals. Typical standby and active currents are only 5 nA and 175 µA resp. The device makes it possible to have a single I2C bus while addressing up to eight different devices. It features single supply operation over 2,7 to 5,5 V, and offers on-board sample and hold circuitry in addition to self-timed conversions. For given 12 bit accuracy it consumes less power industry standard. Operates within standard industrial temperature range.
