FEATURES
• Designed for medium power applications.
• When all terminals are connected to matched loads, no
heatsinking is required. However, if the two inputs are largely out
of phase, or if the device will be subjected to open or short-
circuited loads, an appropriate heat sink is recommended to
maintain rated power.
