Stand-Alone Connection Diagrams
The power supply range is 2.5 V to 5.5 V and isolated RO/MO+ and LO/MO–
lines for BTL operation are required.
Note that the source of any shutdown signal applied to the EVM SHUTDOWN
pin must be able to sink the current flowing through the pullup resistor on the
module (100 k
Ω
) when the pin is held low.
