EP
The Exposed Pad (EP) on the QFN32 package bottom is thermally connected to the
die for improved heat transfer out of package. The exposed pad must be attached to a
heatsinking conduit. The pad is electrically connected to the die, and must be elec-
trically connected to GND.
1. In the differential configuration when the input termination pins (VT0, VT1, VT2, VT3) are connected to a common termination voltage or left
open, and if no signal is applied on INx / INx input, then the device will be susceptible to selfoscillation.
2. All VCC, and GND pins must be externally connected to a power supply for proper operation.
