NXP Semiconductors NAFE11388-EVB Evaluation Board

NXP Semiconductors NAFE11388-EVB Evaluation Board evaluates the NAFE11388 industrial-grade 8-channel universal input analog front-end (AFE). The NXP AFE meets high-precision measurement requirements. The software-defined factory is enabled by NXP's N-AFE analog front end. Beyond Industry 4.0, Manufacturing today is facing a significant transformation called Industry 4.0. Market demands like increased product variability are changing production. To meet these demands, a way to reconfigure production lines to run promptly is needed to maintain profit margins. The ability of smart factories to reconfigure is key. N-AFE analog front-end targeting factory automation applications can be configured for different inputs like voltage, current, resistance, RTD, and more to enable a software-defined factory.
