ADAS1000-3/ADAS1000-4能够测量心电图(ECG)信号、胸阻抗、起搏伪像及导联连接/脱落状态，并将此信息以数据帧的形式输出，以可编程数据速率提供导联/矢量或电极数据。它具有低功耗和小尺寸特性，适合电池供电的便携式应用。它还是一款高性能器件，因此适用于高端诊断设备。
The ADAS1000-4 is a full-featured 3-channel ECG with integrated breathing and pulse detection capabilities; The ADAS1000-3 only provides ECG channels and does not have breathing and pulse detection functions.
The ADAS1000-3/ADAS1000-4 is designed to simplify the task of acquiring and ensuring high-quality ECG signals. These devices provide a low-power, compact data acquisition system for bioelectrical signaling applications. It also has several acquisition quality auxiliary features that help improve the ECG signal, including: multi-channel mean-driven leads, optional reference drives, fast overload recovery, flexible breathing circuitry for return amplitude and phase information, built-in pacing signal detection algorithms running on three leads, and AC or DC lead drop-off detection options. Multiple digital output options ensure flexibility in monitoring and analyzing signals. Cardiac post-processing is a value-added feature that can be performed on an external DSP, microprocessor, or FPGA.
Due to the wide range of applications of ECG systems, the ADAS1000-3/ADAS1000-4 adopts a power/noise adjustment structure to reduce noise at the expense of higher power consumption. To save power, the signal acquisition channel can be turned off or the data rate can be reduced.
To simplify manufacturing test, development, and provide overall power-up testing, the ADAS1000-3/ADAS1000-4 has a number of features, such as DC and AC test excitation via calibrated DAC, CRC redundancy testing, and readback of all relevant register address spaces.
The input structure is a differential amplifier input, allowing users to choose from different configuration schemes for optimal applications.
The ADAS1000-3/ADAS1000-4 are available in two package options: 56-pin LFCSP and 64-pin LQFP; Rated temperature range from -40°C to +85°C.
