A few days ago, Texas instruments (TI) announced the launch of 5 for biological potential application of comprehensive sets measuring AFE molding, further strengthened its the award-winning ADS1298 simulation front (AFE) products camps. The electrocardiogram (ECG) and electroencephalogram (EEG) AFE is the first through the 1 to 2 channels provide 16 and 24 a resolution of the products. Compared with FenLiShi scheme, these devices can be RuiJiang power consumption by more than 94%, the required 86% lower level board space, can meet the portable medical, sports and fitness equipment needs, set long battery life, smaller and lighter and more portable in one body.
 

The main features of the latest AFE and advantages:

:Narrow space board level, reduce the system complexity and power consumption: integrated low noise programmable gain amplifier (PGA), test signal, the right leg drives amplifier, oscillators, voltage reference and sustained break detection function, can be simplified design and greatly reduce board level space, will power consumption RuiJiang to each channel of only 335 uW;
 

:Meet AAMI and IEC requirements: input reference noise uVpp insufficient 8, comply with the association for the promotion of medical devices (AAMI) and the international electrotechnical commission (IEC) terminal equipment performance requirements;
 

:Maximize designed repeated utilization rate: pin compatible, can help customers in the terminal product series maximization repeated use the number of design scheme.
 

Typical application

  Latest ADS1298 series of common applications include AFE dynamic ecg and fitness heart rate monitor, etc. For these applications in, the customer may have the following power and space save advantage:

  Based on the ADS1292, dual channel dynamic electrocardiogram products and FenLiShi implementation plan, compared to 94% lower power consumption, board level space reduced by 92%, and a 92% decrease in the number of components;
 

  In typical heart rate monitors for fitness, ADS1291 score vertical implementation plan 89% less power consumption, board level space reduced by 52%, and a 75% decrease in the number of components.
 

  ADS1298 series of various devices highly integrated medical fitness application all the important function, can help clients focus on developing the firmware, through the FDA certificate and carry out the scene the type, need not for the hardware design distractions.

Tools and support

   TI provide a wide variety of tools and support accelerating the development of all ADS1298 series, including validation circuit board signal integrity demand model and speed up the IBIS evaluation evaluation board (EVM). But the latest AFE EVM immediate purchase include:

Evaluation and ADS1192 ADS1192ECG-ADS1191 of FE;
Evaluation and ADS1292 ADS1292ECG-ADS1291 of FE;
And the ADS1292RECG FE-ADS1291R assessment.

  In addition, the use of ADS1298 series design engineers can also through the TI E2E ? community of high precision simulation data converter BBS consulting problem.
 

Availability and packaging

  The 7 mm x 7 mm TQFP encapsulates the latest AFE (16 a single channel ADS1191, 16, 24 ADS1192 double channel a single channel ADS1291, 24 bits dual channel ADS1292 and support the impedance of the 24 bits breathing dual channel ADS1292R) have now supply.

ADS1298 AFE series

  ADS1298 ECG/EEG AFE series with its outstanding innovation design has won EDN China, the electronic engineering album, electronic system design, today's electronic and EN-Genius and other media of all kinds of honor awarded. In addition to the latest single channel 16 and 24 bits AFE besides, still can ADS1298 series for high performance and high performance medical diagnosis and research level ECG/EEG equipment with 24 bits 8 channels, 6 channels and 4 channel AFE, in view of the low cost high performance medium power consumption equipment with 16 ECG 8 channel, and channel 4 and 6 AFE channel.
