10-bit serial A/D converter, 4-channel, 2.7V, SPI, SO-14

MCP3004
2.7V 4-channel 10-bit A/D converter with SPI™ serial interface

Description:
The company Microchip Technology Inc. MCP3004/3008 devices are sequential proximity 10-bit analog-to-digital converters (A/D converters) with integrated sensing and holding circuitry. The MCP3004 is programmable to provide two pseudo-differential input pairs or four unbalanced inputs. The MCP3008 is programmable to provide four pseudo-differential input pairs or eight unbalanced inputs. Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) are specified with ±1 LSB. Communication with the devices is via a simple serial interface that is compatible with the SPI protocol. The devices are capable of achieving conversion rates of up to 200 ksps. The MCP3004/3008 modules operate over a wide voltage range (2.7V - 5.5V). The low-current design allows operation with typical standby currents of only 5 nA and typical active currents of 320 µA.The MCP3004 is offered in 14-pin PDIP, 150 mil SOIC and TSSOP packages, while the MCP3008 is available in 16-pin PDIP and SOIC packages.
