MCP3001 is a successive approximation 10-bit A/D converter (ADC) with onboard sample and hold circuitry. The device provides a single pseudo-differential input. Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) are both specified at ±1 LSB max. Communication with the device is done using a simple serial interface compatible with the SPI protocol. The device is capable of sample rates up to 200 ksps at a clock rate of 2.8 MHz. The MCP3001 operates over a broad voltage range (2.7V - 5.5V). Low current design permits operation with a typical standby current of only 5 nA and a typical active current of 400 µA. The device is offered in 8-pin PDIP, MSOP, TSSOP and 150 mil SOIC packages.
