NXP® solutions power next-generation digital stethoscopes, which filter and amplify cardiac signals and then display chart results in a graphic interface. These improvements help doctors make more accurate diagnoses.
NXP offers 8-bit and 32-bit ultra-low-power MCUs with the ability to drive an LCD display—ideal for improving portability of digital stethoscope designs, as well as for more challenging applications like fetal heart rate monitors.
Speed development time when designing your portable medical device with Our Healthcare Analog Front End (AFE) reference platform which includes a complete hardware platform, schematics and software. Based on the Kinetis Microcontroller K53 measurement.
