Biopotential sensor ICs provide electrocardiogram (ECG) waveforms, heart rate/pacemaker edge detection, and bioimpedance (BioZ) measurements with clinical-grade accuracy (IEC 60601-2-47).
Our biopotential sensors deliver highly integrated analog front-end (AFE) solutions for complete ECG and BioZ recordings while consuming the lowest power. Typical applications include cardiac health monitoring, heart-rate monitoring, arrhythmia detection, stress test applications, and respiration monitoring. Wafer-level packages (WLPs) support small form factors in wearable applications such as medical patches, wrist-worn devices, and chest-strap heart-rate monitors.
Key Features Include:
- Low-power operation for continuous monitoring
- Integrated ECG, bioimpedance, PACE detect and R-R algorithm
- Small-size solutions, with pin-compatible packages
- Clinical-grade measurement (meets IEC60601-2-47)
