Description

The Microchip Technology Inc. MCP3004/3008 devices are successive approximation 10-bit Analog- to-Digital (A/D) Converters with on-board sample and hold circuitry. The MCP3004 is programmable to provide two pseudo-differential input pairs or four single- ended inputs. The MCP3008 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 done using a simple serial interface compatible with the SPI protocol. The devices are capable of conversion rates of up to 200ksps. The MCP3004/3008 devices operate over a broad voltage range (2.7V - 5.5V). Low current design permits operation with typical standby currents of only 5nA and typical active currents of 320A. The MCP3004 is offered in 14-pin PDIP, 150mil SOIC and TSSOP packages, and the MCP3008 is offered in 16-pin PDIP and SOIC packages.
