Product Details

The ADAS1000-1 is a 5 electrode ECG analog front end designed to measure electro cardiac ECG signals and lead-on/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 ADAS1000-1 is one of the family of ADAS1000 generics tailored for ECG applications, the ADAS1000-1 has a subset of features of the family. The ADAS1000 family are 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, these products feature a power/ noise scaling architecture where the noise can be reduced at the expense of increasing power consumption. Signal acquisition channels may 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 ADAS1000-1 offers a suite of features, such as dc and ac test excitation via the calibration DAC and 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 ADAS1000-1 is available in a 56-lead LFCSP package and is specified over −40°C to +85°C temperature range.
