Product Details

The AD8233CB-EBZ evaluation board contains an AD8233 heart rate monitor (HRM) front end conveniently mounted with the necessary components for initial evaluation in fitness applications. Inputs, outputs, supplies, and leads off detection terminals are routed to test pins to simplify connectivity. Switches and jumpers are available for setting the input bias voltage, shutdown (SDN), right leg drive shutdown (RLD SDN), fast restore (FR), and ac/dc leads off detection mode.

The AD8233CB-EBZ evaluation board is a 4-layer board with components mounted on the primary side only. Rubber feet are available on the secondary side for mechanical stability. The layout diagrams are provided as a visual aid and reference design. The printed circuit board (PCB) is designed following standard practices to ensure signal integrity and reduce manufacturing costs. For best WLCSP layout practices, refer to AN-617.

Full details about the AD8233 are available in the AD8233 data sheet, which is available from Analog Devices, Inc., and should be consulted in conjunction with this user guide when using this evaluation board.
