The circuit shown can be used to interface multiple serial devices to the I2C bus, even if they lack the extended-addressing capability required. Information transfer be-tween I2C devices connected to ...

The 12-bit MCP3221 analog-to-digital converter (ADC) incorporates an I2C interface in an SOT-23 package. The 400-kHz clock rate of the two-wire serial, I2C interface enables sampling rates up to 22.3 ...
