The ADAS1000-1BCPZ-RL measures electrocardiac (ECG) signals, thoracic impedance, pacing artifacts,and lead-on/lead-off status and output this information in theform of a data frame supplying either lead/vector or electrodedata at programmable data rates. Its low power and small sizemake it suitable for portable, battery-powered applications.The high performance also makes it suitable for higher enddiagnostic machines.
The ADAS1000-1BCPZ-RL is a full-featured, 5-channel ECG includingrespiration and pace detection, while the ADAS1000-1 offersonly ECG channels with no respiration or pace features. Similarly,the ADAS1000-2 is a subset of the main device and is configuredfor gang purposes with only the ECG channels enabled (norespiration, pace, or right leg drive).
The ADAS1000/ADAS1000-1/ADAS1000-2 are designed tosimplify the task of acquiring and ensuring quality ECG signals.They provide 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. Severaldigital output options ensure flexibility when monitoring andanalyzing signals. Value-added cardiac post processing isexecuted externally on a DSP, microprocessor, or FPGA.Because ECG systems span different applications, theADAS1000/ADAS1000-1/ADAS1000-2 feature a power/noisescaling architecture where the noise can be reduced at theexpense of increasing power consumption. Signal acquisitionchannels can be shut down to save power. Data rates can bereduced to save power.
To ease manufacturing tests and development as well as offerholistic power-up testing, the ADAS1000/ADAS1000-1/ADAS1000-2 offer a suite of features, such as dc and ac testexcitation via the calibration DAC and cyclic redundancy check(CRC) redundancy testing, in addition to readback of allrelevant register address space.The input structure is a differential amplifier input, therebyallowing users a variety of configuration options to best suittheir application.
The ADAS1000/ADAS1000-1/ADAS1000-2 are available in twopackage options, a 56-lead LFCSP package and a 64-lead LQFPpackage. Both packages are specified over a −40°C to +85°Ctemperature range.
