ADAS1000-1is a 5-electrode ECG analog front end capable of measuring electrocardiogram (ECG) signals and lead-connect/drop-off states and outputting this information as a data frame to provide lead/vector or electrode data at a programmable data rate. It features low power consumption and small size, making it suitable for battery-powered portable applications. It is also a high-performance device, making it suitable for high-end diagnostic equipment.
The ADAS1000-1 belongs to the ADAS1000 family of products and is customized for ECG applications and has some of the features of this family of products. The ADAS1000 family of products is designed to simplify the task of acquiring and ensuring high quality ECG signals. These devices provide a low-power, small data acquisition system for bioelectric signal applications. It also has a number of auxiliary features that help improve the acquisition quality of ECG signals, including: multichannel mean driven leads, optional reference drive, fast overload recovery, flexible breathing circuits that return amplitude and phase information, built-in pacing signal detection algorithms running on three leads, and AC or DC lead drop detection options. Multiple digital output options ensure flexibility in monitoring and analyzing signals. Cardiac after-processing is a value-added feature that can be used in external DSPs,microprocessoror executed on the FPGA.
Due to the wide range of ECG systems, these products employ a power/noise scaling architecture to reduce noise at the expense of increased power consumption. To save power, the signal acquisition channel can be turned off or the data rate can be reduced.
To simplify manufacturing testing, development, and provide overall power-up testing, the ADAS1000-1 includes features such as calibrated DACs to provide dc and ac test stimulus, CRC redundancy testing, and readback of all relevant register address spaces.
The input structure is differential amplifier input, allowing the user to select different configuration schemes to achieve the best application.
The ADAS1000-1 is available in a 56-lead LFCSP package and is specified over the −40°C to +85°C temperature range.
