Healthcare sensor ICs use current or optics to sense the human body’s vital signs. Typically, these biosensors condition the signal and send it to a microprocessor for storage, calculation, or display by a health monitoring device.

Our healthcare sensor solutions are ideal for portable medical and wellness applications, as well as wearable medical and fitness applications. Low-power operation fosters longer battery life. These highly integrated sensor ICs reduce the total solution chip count by including analog front-ends (AFEs), ADCs, and ESD/EMI protection circuitry with key features such as:

  • Clinical-grade performance for temperature and ECG measurements
  • High dynamic range AFEs with low SNR
  • Complete optical modules for a variety of applications
  • Built-in algorithms
