EP
The Exposed Pad (EP) on the QFN16 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 electrically and thermally con-
nected to GND on the PC board.
1. In the differential configuration when the input termination pin (VT) is connected to a common termination voltage or left open, and if no signal
is applied on IN / IN input, then, the device will be susceptible to selfoscillation.
2. All VCC, VCCO and GND pins must be externally connected to a power supply for proper operation.
