Biosensing AFEs

Integrated AFE ICs for photoplethysmography (PPG), electrocardiography (ECG), electroencephalography (EEG) & impedance cardiography (ICG)

parametric-filterView all products
Our analog front ends have a strong heritage of use in the clinical and wellness market space.  Our portfolio of biosensing AFEs offers an entire standalone and multi-modal analog signal chain for ECG, PPG, EEG, and ICG.  For wearables and multi-modal sensing needs, TI has integrated all PPG, ECG and ICG signal chains into one device.  All the AFEs are designed to solve analog signal conditioning and A/D conversion channels, while allowing for scalability and maximum flexibility allowing the designer to optimize sensor design and industrial design for their needs.

Designed with your challenges in mind


Faster design time

These AFEs integrate signal conditioning circuits, references, clocks, ADC, FIFOs and many digital filters that allow you to spend more time testing and tweaking rather debugging fundamental circuits.



AFEs offer best-in-class analog peformance, but also provide enough  adjustments to help you differentiate not only with algorthms but also in sensor and industrial designs.


Platform & scalability

Each family of AFEs offers products that enable designers to design once for the needs of high-, mid- and low-end products with minimal firmware and BoM changes.
