FUNCTION
MODE Input. Leave MODE input unconnected to select low quiescent current mode to support
CENELEC applications. Pull MODE input high to select higher quiescent current mode to support
FCC and ARIB applications. See the Bias Selection section for more details.
Transmit Enable. Pull TXEN high to enable the amplifier outputs. Tie TXEN to DGND to disable
the amplifier outputs. See the Output Enable section.
Current-Limit Setting Input. Connect a resistor between ILSET and AGND to set the current limit
for the outputs. See the Protection and Diagnostics section.
