Description

The Microchip Technology Inc. MCP3001 is a successive approximation 10-bit A/D converter (ADC) with on-board sample and hold circuitry. The MCP3001 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 of up to 200ksps at a clock rate of 2.8MHz. The MCP3001 operates over a broad voltage range (2.7V - 5.5V). Low current design permits operation with a typical standby current of only 5nA and a typical active current of 400A. The device is offered in 8 pin PDIP, TSSOP and 150mil SOIC packages.
