DESCRIPTION

The Microchip Technology’s. MCP3201 is a successive approximation 12-bit Analog-to-Digital (A/D) Converter with on-board sample and hold circuitry. The device provides a single pseudo-differential input. Differential Nonlinearity (DNL) is specified at ±1 LSB, and Integral Nonlinearity (INL) is offered in ±1 LSB (MCP3201-B) and ±2 LSB (MCP3201-C) versions. 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 100ksps at a clock rate of 1.6MHz. The MCP3201 operates over a broad voltage range (2.7V – 5.5V). Low current design permits operation with typical standby and active currents of only 500nA and 300µA, respectively.
