The digital stethoscope is a step forward from its counterparts, with the capability of filtering and amplifying the signal. It connects to a LCD display to chart the results and have a graphic interface.
Improvement of listening to cardiac sounds helps a doctor make a more accurate diagnosis.
Freescale offers 8-bit and 32-bit ultra-low-power MCUs with the ability to drive an LCD display, ideal for the portability of digital stethoscopes and for more challenging applications such as fetal heart rate monitors.
Speed development time when designing your portable medical device with Freescale's Healthcare Analog Front End (AFE) reference platform which includes a complete hardware platform, schematics and software. Based on the Kinetis Microcontroller K53 measurement.See more demos at the Freescale Community >
