AFE enables size/power breakthroughs for portable ECG/EEG devices

In innovative patient-monitoring equipment, such as portable medical, space is vital. Making it a great fit for portable ECG/EEG equipment, Texas Instruments’ ADS1298 analog-front end ( www2.electronicproducts.com/AFE_for_ECG_EEG_apps_ reduces_component_count_power_consumption-article-hlcn02_may2010-html.aspx) uses up to 95% fewer components than discrete solutions while integrating all common features required for ECG/EEG front ends. At a very low price when compared to others ($23.95 in 1,000-piece lots), the savings for both component count and board space are extremely significant.

Power and noise are two more key concerns for medical diagnostic equipment. With the device’s power consumption of 1 mW/channel, up to 95% less power is used than discrete implementations, equipment portability increases and patient mobility as well as longer term monitoring capability improves. The ADS1298’s 4-µVp-p (average) input-referred noise surpasses the limits set in IEC60601-2-27/51, which provides more accurate measurements in portable equipment and high-channel-density medical equipment.

The ADS1298 was essentially developed to streamline ECG system design. Among its attributes, the device can detect pulses made by a cardiac pacemaker with an ECG signal, as well as report when a sensor lead is improperly attached to the patient, two critical actions that can save patient lives.
