ADAS1000:  Low Power, 5-Electrode Electrocardiogram (ECG) Analog Front End with respiration measurement and pace detection)

Product Details

Product Status:Recommended for New Designs

The ADAS1000 measures electro cardiac (ECG) signals, thoracic impedance, pacing artifacts, lead on/off status and outputs 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 designed to simplify the task of acquiring and ensuring quality ECG signals. Value-added cardiac postprocessing is executed externally on a DSP, microprocessor or FPGA. Several digital output options ensure flexibility when monitoring and analyzing signals. The ADAS1000 provides a low power, small data acquisition system for biopotential applications.

Auxiliary features that aid in better quality ECG signal acquisition include: multi-channel averaged driven lead, selectable reference drive, fast over load recovery, flexible respiration circuitry returning magnitude and phase information, internal pace detection algorithm operating on 3 leads and option of AC or DC leads off detection.

Since ECG systems span different applications, the ADAS1000 features a flexible power/noise scaling architecture where the noise can be reduced at the expense of increasing power consumption. Signal acquisition channels may be shutdown to save power. Data rates can be reduced to save power.

To ease manufacturing tests, development, as well as offer holistic power-up testing, the ADAS1000 offers a suite of dc and ac test excitation via the CAL DAC, CRC redundancy testing in addition to read-back of all relevant register address space.

The ADAS1000 is available in two package options, either a 56 lead LFCSP or a 64 lead LQFP package and is specified over -40°C to +85°C temperature range. The ADAS1000 is a full featured 5 channel ECG including respiration and pace detection, while the ADAS1000-1 offers only ECG channels with no respiration or pace features. Similarly the ADAS1000-2 is a subset of the main device and is configured for gang purposes with only ECG channels enabled (no respiration, pace, RLD, etc).
