The ADAS1000 measures electro cardiac (ECG) signals, thoracic impedance, pacing artifacts, and lead-on/lead-off status and output this information in the form of a data frame supplying either lead/vector or electrode data at programmable data rates. Its low power and small size make it suitable for portable, battery-powered applications. The high performance also makes it suitable for higher end diagnostic machines.The ADAS1000 is a full-featured, 5-channel ECG including respiration and pace detection, while theADAS1000-1offers only ECG channels with no respiration or pace features. Similarly, theADAS1000-2is a subset of the main device and is configured for gang purposes with only the ECG channels enabled (no respiration, pace, or right leg drive). The ADAS1000/ADAS1000-1/ADAS1000-2are designed to simplify the task of acquiring and ensuring quality ECG signals. They provide a low power, small data acquisition system for biopotential applications. Auxiliary features that aid in better quality ECG signal acquisition include multichannel averaged driven lead, selectable reference drive, fast overload recovery, flexible respiration circuitry returning magnitude and phase information, internal pace detection algorithm operating on three leads, and the option of ac or dc lead-off detection. Several digital output options ensure flexibility when monitoring and analyzing signals. Value-added cardiac post processing is executed externally on a DSP, microprocessor, or FPGA.Because ECG systems span different applications, the ADAS1000/ADAS1000-1/ADAS1000-2feature a power/noise scaling architecture where the noise can be reduced at the expense of increasing power consumption. Signal acquisition channels can be shut down to save power. Data rates can be reduced to save power.To ease manufacturing tests and development as well as offer holistic power-up testing, the ADAS1000/ADAS1000-1/ADAS1000-2offer a suite of features, such as dc and ac test excitation via the calibration DAC and cyclic redundancy check (CRC) redundancy testing, in addition to readback of all relevant register address space.The input structure is a differential amplifier input, thereby allowing users a variety of configuration options to best suit their application.The ADAS1000/ADAS1000-1/ADAS1000-2are available in two package options, a 56-lead LFCSP package and a 64-lead LQFP package. Both packages are specified over a −40°C to +85°C temperature range.ApplicationsECG: Monitor & DiagnosticBedside Patient MonitoringPortable TelemetryHolterAEDCardiac DefibrillatorsAmbulatory MonitorsPace Maker ProgrammerPatient TransportStress testing
