... For a 13-bit converter, the theoretical SNR limit is 80.02 dB. Total Harmonic Distortion - Total Harmonic Distortion is (THD) is the ratio of the rms sum of the harmonics to the fundamental, measured at the output of the con- verter. For the MCP3301 defined using the first 9 harmonics, as shown in the following equation: EQUATION ...

... Simplified Block Diagram. DS21700C-page 16 6.2 Driving the Analog Input The analog input of the MCP3301 is easily driven either differentially or single-ended. Any signal that is com- mon to the two input channels will be rejected by the common mode rejection of the device. During the charging time of the sample capacitor, a small charging current will be required ...

... Analog Input Model. 6.2.1 MAINTAINING MINIMUM CLOCK SPEED When the MCP3301 initiates, charge is stored on the sample capacitor. When the sample period is complete, the device converts one bit for each clock that is received important for the user to note that a slow clock rate will allow charge to bleed off the sample capacitor while the conversion is taking place ...

... Communicating with the MCP3301 Communication with the device is completed using a standard SPI compatible serial interface. Initiating com- munication with the MCP3301 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 communication ...

... For example, Figure 7-4 and Figure 7-5 show how the MCP3301 can be interfaced to a microcontroller with a standard SPI port. Since the MCP3301 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 MCP3301 ...
