The MCP3008-I/SL is an 8 channel, 10bit Analogue to Digital (ADC) Converter with SPI interface in 16 pin SOIC package. This ADC combines high performance and low power consumption in a small package by making it as an ideal for embedded control applications. The MCP3008 features successive approximation register (SAR) architecture with onboard sample and hold circuitry allowing 10bit ADC capability to be added to any PIC microcontroller. 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 ±1LSB. Communication with devices is accomplished using simple serial interface compatible with SPI protocol. Low current design permits operation with typical standby currents of only 5nA (2µA maximum) and typical active currents of 320µA (500µA maximum).
