Stand-Alone Connection Diagrams
2-7 Operation
2.4 Stand-Alone Connection Diagrams
The power supply range is 4.5 V to 5.5 V and isolated RO/MO+ and LO/MO–
lines for BTL operation are required.
Note that the shutdown signal applied to the EVM SHUTDOWN pin must be
able to supply enough current to overcome the pullup resistor on the module
(100 k
Ω
).
