Kit Overview

The Analog Devices EVAL-ADAS1000SDZEVAL-ADAS1000SDZ is a fully featured evaluation kit for the ADAS1000ADAS1000. The evaluation kit consists of an evaluation board kitted with 2 ADAS1000 devices capable of demonstrating ECG capture up to 12 leads. Included in the kit is a medical grade +5V wall adaptor with interchangeable worldwide wall plugs and a CD with user software for data capture and display. The software allows control of all ADAS1000 registers, ability to capture and display ECG data, respiration data, pace pulse detection and store data for offline processing.

This evaluation board is provided for silicon evaluation purposes and is not designed to be connected directly to animal or human. This board operates in conjunction with the System Development Platform (SDP) or alternatively may be interfaced to directly via a dedicated serial interface connector (J4). It does not come as part of the evaluation kit and can be ordered separately (EVAL-SDP-CB1ZEVAL-SDP-CB1Z). It can be reused with many other Analog Devices evaluation modules.

The SDP controller board connects to the PC via USB 2.0. The evaluation board connects to the SDP controller board. The ADAS1000 evaluation boardADAS1000 evaluation board cannot be connected directly to the PC. The evaluation software running on the PC will communicate with the evaluation board through the SDP Controller board.

The primary function of the EVAL-ADAS1000 evaluation boardEVAL-ADAS1000 evaluation board is to demonstrate the ADAS1000ADAS1000 integrated ECG device for medical instrumentation. This evaluation board is used to evaluation the ADAS1000 and all variants.

The evaluation board is ideal for exploring concepts and adopting the ADAS1000ADAS1000 into advanced medical systems. The board can be operated as part of an end user’s system via the ADAS1000 SPI interface or as a standalone evaluation of the ADAS1000 using the support of the Analog Devices system demonstration platform controller board (SDP-B), , and a standard PC (running Windows XP, Windows Vista or Windows 7 32-bit and 64-bit) to run the Analog Devices evaluation software.

The SDP-B board, which is a DSP-based controller board is separate from the evaluation board, is required to run the Analog Devices evaluation software and is used for data transfer from evaluation board to PC via USB interface. It does not come as part of the evaluation kit and can be ordered separately (EVAL-SDP-CB1ZEVAL-SDP-CB1Z). It can be reused with many other Analog Devices evaluation modules.

Key Applications: ECG, Patient monitor, Holter monitor, Cardiac defibrillators

Software Development Tools:

ADAS1000 Evaluation Software

The evaluation kit for the ADAS1000 includes self-installing software on the CD. The software is compatible with Windows XP, Windows Vista (32-bit), and Windows 7 (32-bit and 64-bit). The software must be installed before connecting the SDP board to the USB port of the PC to ensure that the SDP board is recognized when it connects to the PC. The software allows access to all register controls, streaming (ECG, respiration, pace, and lead off), and the write to file window.

Hardware Development Tools:

SDP-B Controller Board

The SDP-B is a controller board for the System Demonstration Platform (SDP). The SDP-B is based on the Blackfin ADSP-BF527 processor with connectivity to the PC through a USB 2.0 high speed port. Controller boards allow for the configuration and capture of data on daughter boards from the PC via USB.The SDP-B (EVAL-SDP-CB1ZEVAL-SDP-CB1Z) is the required controller board for this evaluation system.Evaluation boards requiring the SDP-B will not work with the SDP-S controller board.
