Industrial vibration sensing is a crucial process incondition monitoring, which is necessary for predictivemaintenance. An integrated electronic piezoelectric(IEPE) sensor is the most common vibration sensorused in the industrial environment. The TIDA-01471design is a full analog front end for the IEPE sensorinterface and demonstrates how to achieve flexiblehigh-resolution, high-speed conversion with low-powerand small-footprint implementation.
