The MCP3008 device is a successive approximation 10-bit analog-to-digital converter with an onboard sample and holds circuitry. It is programmable to provide four pseudo-differential input pairs or eight single-ended inputs. Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) are specified at ±1 LSB. Communication with the devices is accomplished using a simple serial interface compatible with the SPI protocol.
