Analog data acquisition card MCC 172

multifunction

The MCC 172 is a two channel DAQ HAT for making sound and vibration measurements from IEPE sensors like accelerometers and microphones. It features a 24-bit A/D per channel and a maximum sample rate of 51.2 kS/s/Ch. Up to eight MCC HATs can be stacked onto one Raspberry Pi allowing users to create high-channel count, multifunction solutions of different signal types. All MCC DAQ HATs include easy-to-use C/C++® and Python™ open-source libraries and examples for taking reliable, quality measurements quickly. Raspberry Pi Interface The MCC 172 header plugs into the 40-pingeneral purpose I/O (GPIO) connector on auser-supplied Raspberry Pi. The MCC 172was tested for use with all Raspberry Pimodels with the 40-pin GPIO connector. HAT Configuration HAT configuration parameters are storedin an on-board EEPROM that allows theRaspberry Pi to automatically set up theGPIO pins when the HAT is connected. Stackable HATs Up to eight MCC HAT boards can bestacked onto a single Raspberry Pi.Users can mix and match MCC HATmodels in the stack.Analog InputThe two 24-bit differential analog inputchannels simultaneously acquire data atrates up 51.2 kS/s. Users can turn IEPEexcitation current on or off. Each channel has a dedicated A/D converter. Both ADCs share the same clockand are synchronized to start conversionsat the same time for synchronous data. Multiple HAT SynchronizationMultiple MCC 172 HATs can be synchronized to a single sampling clock. The clock isprogrammable for sampling rates between51.2 kS/s to 200 S/s.
