MCP3208: 12bit eight channel ADC with SPI interface
The Microchip Technology Inc. MCP3208 devices are successive approximation 12-bit Analog-to-Digital (A/D) Converters with on-board sample and hold circuitry. The MCP32084 is programmable to provide four pseudo-differential input pairs or eight single-ended inputs. Differential Nonlinearity (DNL) is specified at ±1 LSB, and Integral Nonlinearity (INL) is offered in ±1 LSB (MCP3208B) and ±2 LSB (MCP3208C) versions. Communication with the devices is done using a simple serial interface compatible with the SPI protocol. The devices are capable of conversion rates of up to 100ksps. MCP3208 ADC operates over a broad voltage range (2.7V -5.5V). Low current design permits operation with typical standby and active currents of only 500nA and 320µA, respectively. The MCP3208 is offered in 14-pin PDIP, 150mil SOIC and TSSOP packages.
