with the MBa117xL
The acquisition of analog measured values at the edge is becoming more and more important. An analog front end for precise and problem-free acquisition of voltage, current and resistance, directly where they occur, is the most reliable way to meet the requirements of both measurement and computer technology.
The MBa117xL single-board computer has an analog front end in the form of NXP's NAFE13388 and is therefore in line with the trend and opens up numerous new application possibilities - without requiring complicated external circuitry.
The analog front-end includes two fast voltage multiplexers with low leakage current, PGA (Programmable Gain Amplifier) and buffer with low offset and low drift, a precise 24-bit delta sigma ADC with high data rate and a voltage reference with low drift.
The analog voltage inputs are diode-protected for EMI and miswiring scenarios, and the device is also equipped with diagnostic circuits for functional safety and monitoring and detection. Current/voltage sources are implemented for loop-back measurements or providing low-drift output bias. Two precise calibration voltage sources are available for end-to-end system self-calibration and anomaly detection for predictive maintenance.
Thus, the analog front end supports the module in the edge application, i.e. exactly where the analog data of the real world occur. Thanks to its numerous interfaces, MBa117xL can flexibly transfer the analog measured values into the digital world. Furthermore, the MBa117xL is suitable to realize the reaction of the digital world in the real world, for example by controlling actuators.
All this is pre-integrated in a user-friendly way and makes MBa117xL fit for new solution approaches and helps to optimize countless application possibilities and processes or to develop completely new applications. Various applications in smart and safe factory automation, medical technology, infrastructure projects and building automation benefit from this.
