The ADAS1000-3/ADAS1000-4 measure electro cardiac (ECG)signals, thoracic impedance, pacing artifacts,and lead-on/off status and output this information in the formof a data frame supplying either lead/vector or electrode data atprogrammable data rates. Its low power and small size make itsuitable for portable, battery-powered applications. The highperformance also makes it suitable for higher end diagnosticmachines.
The ADAS1000-4 is a full-featured, 3-channel ECG includingrespiration and pace detection, while the ADAS1000-3 offersonly ECG channels with no respiration or pace features.
The ADAS1000-3/ADAS1000-4 are designed to simplify thetask of acquiring and ensuring quality ECG signals. Theyprovide a low power, small data acquisition system forbiopotential applications. Auxiliary features that aid in betterquality ECG signal acquisition include: multichannel averageddriven lead, selectable reference drive, fast overload recovery,flexible respiration circuitry returning magnitude and phaseinformation, internal pace detection algorithm operating onthree leads, and the option of ac or dc lead-off detection.Several digital output options ensure flexibility whenmonitoring and analyzing signals. Value-added cardiac postprocessing is executed externally on a DSP, microprocessor, orFPGA.
Because ECG systems span different applications, theADAS1000-3/ADAS1000-4 feature a power/noise scalingarchitecture where the noise can be reducedat the expense of increasing power consumption. Signalacquisition channels may be shut down to save power. Datarates can be reduced to save power.
To ease manufacturing tests and development as well as offerholistic power-up testing, the ADAS1000-3/ADAS1000-4 offera suite of features, such as dc and ac test excitation via thecalibration DAC and CRC redundancy testing in addition toreadback of all relevant register address space.
The input structure is a differential amplifier input therebyallowing users a variety of configuration options to best suittheir application.
The ADAS1000-3/ADAS1000-4 are available intwo package options: either a 56-lead LFCSP or a 64-leadLQFP package; they are specified over −40°C to +85°Ctemperature range.
