The MCP3208 IC is an 8-channel, 12-bit Analogue to Digital Converter (ADC) with an SPI interface in a 16-pin DIP package. This ADC combines high performance and low power consumption in a small package making it ideal for embedded control applications.
It features successive approximation register (SAR) architecture with onboard sample and hold circuitry allowing 12-bit 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) is specified at ±1LSB and integral nonlinearity (INL) is ±2LSB. Communication with devices is accomplished using a simple serial interface compatible with SPI protocol. Low current design permits operation with typical standby and active currents of only 500nA (2μA maximum) and 320μA (400μA maximum) respectively.
