Product Details

The user guide describes the operation of the EVAL-ADPD7000Z demonstration kit, which is an evaluation module for the ADPD7000.

The ADPD7000 is a fully Integrated analog front end (AFE) for wearable vital signal monitoring (VSM) devices. The key functions of the ADPD7000 include photoplethysmography (PPG), electrocardiogram (ECG), body impedance analysis (BIA), and electrodermal activity (EDA).

This demonstration kit includes both software and hardware. The EVAL-ADPD7000Z can evaluate the AFE feature and verify the system design based on the AFE. According to the requirements of the application, the user can use a cable connection or Bluetooth connection to establish communication between the PC and the EVAL-ADPD7000Z demonstration kit.

The user guide also describes an example configuration of the different functions of the ADPD7000.

For full details on the ADPD7000, see the ADPD7000 data sheet, which must be consulted in conjunction with the user guide when using the EVAL-ADPD7000Z.
