PERFORMANCE DATA
These performance parameters
are based on module operation at
25°C from a 3.0VDC supply unless
otherwise noted. Figure 2
illustrates the connections
necessary for testing and
operation. It is recommended all
ground pins be connected to the
ground plane. The pins marked NC
have no electrical connection.
