Description 

MCP3004/3008 Microchip devices are having on-chip sampling and holding circuit 10 holds the number of successive approximation (Analog-to-Digital, A / mold D) converter. MCP3004 can be programmed to provide two pseudo-differential input pairs or four single-ended inputs. The MCP3008 can provide four pseudo-differential input pairs or eight single-ended inputs. Differential nonlinearity (Differential Nonlinearity, DNL) and integral nonlinearity (Integral Nonlinearity, INL) are specified as ± 1 LSB. It uses the SPI serial interface simple communication protocol compatible with the device. Conversion rate of the device up to 200 ksps. MCP3004/3008 device has a wide operating voltage range: 2.7V to 5.5V. Low current design allows the device to the typical standby current of 5 nA getting off work or typical operating current of 320 μA condition for. MCP3004 in 14-pin PDIP, SOIC (150 mil) and TSSOP packages available, and MCP3008 16-pin PDIP and SOIC packages.
