Media Mentions

Analog Front End Chip TI is the first to provide a complete family of electrocardiography (ECG) and electroencephalography (EEG) AFEs for applications ranging from portable to diagnostic- and research-grade systems. All devices in the ADS1298 family have low-noise programmable gain amplifiers (PGAs), test signals, a right leg drive amplifier, oscillator, voltage reference and lead-off detection function to simplify design, while significantly reducing board space requirements and cutting power consumption. This level of integration enables customers to focus development efforts on firmware, FDA approvals, field testing and more, rather than hardware design.
