• The Microchip Technology Inc. MCP3004/3008
devices are successive approximation 10-bit Analogto-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 accomplished using
a simple serial interface compatible with the SPI
protocol. The devices are capable of conversion rates
of up to 200 ksps. 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 5 nA and typical active currents of 320 µA. The
MCP3004 is offered in 14-pin PDIP, 150 mil SOIC and …
