MCP3008 8-Channel 10-Bit A/D Converter with SPI Interface IC DIP-16 Package

The Microchip Technology Inc.MCP3008 8-Channel 10-Bit devices are successive approximation 10-bit Analogto-Digital (A/D) converters with on-board sample and hold circuitry.  The MCP3008 is programmable to provide four pseudo-differential input pairs or eight single-ended inputs. Differential Non linearity (DNL) and Integral Non linearity (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 MCP3008 8-Channel 10-Bit 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 MCP3008 is offered in 16- pin PDIP and SOIC packages.
