Healthcare Sensor ICs

Biopotential, Electrochemical, Optical, and Temperature Sensors for Wearable, Fitness, and Medical Applications

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
