... Communication with the device is done using a simple serial interface compatible with the SPI protocol. The device is capable of sample rates 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 cur- rents of only 500nA and 300µ ...

... SERIAL COMMUNICATIONS Communication with the device is done using a stan- dard SPI-compatible serial interface. Initiating commu- nication with the MCP3201 begins with the CS going low. If the device was powered up with the CS pin low, it must be brought high and back low to initiate commu- nication. The device will begin to sample the analog input on the first rising edge after CS goes low ...

... MCP3201 example, Figure 6-1 and Figure 6-2 show how the MCP3201 can be interfaced to a microcontroller with a standard SPI port. Since the MCP3201 always clocks data out on the falling edge of clock, the MCU SPI port must be configured to match this operation. SPI Mode 0,0 (clock idles low) and SPI Mode 1,1 (clock idles high) are both compatible with the MCP3201 ...

... This is illustrated in Figure 6-3 where an op amp is used to drive the analog input of the MCP3201. This amplifier provides a low impedance source for the converter input and a low pass filter, which eliminates unwanted high frequency noise ...
