AN-617 application note
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.
