Description
MCP3201
2.7V 12-Bit A/D Converter with SPI Serial Interface
Description:
The Microchip Technology Inc. MCP3201 device 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 100 ksps at a clock rate of 1.6 MHz. The MCP3201 device operates over a broad voltage range (2.7V - 5.5V). Low-current design permits operation with typical standby and active currents of only 500 nA and 300 µA, respectively. The device is offered in 8-pin MSOP, PDIP, TSSOP and 150 mil SOIC packages.
