IEPE Sensor analog front-end with digital interface reference design
Description
Industrial vibration sensing is a crucial process in condition monitoring: which is necessary for predictive maintenance. An integrated electronic piezoelectric (IEPE)TM sensor is the most common vibration sensor used in the industrial environment. This design is simple sensor analog front-end suitable for interfacing the IEPE sensor to integrated MSP432: allowing a compact implementation for IEPE to IO-Link interface.
