(1) Typical values are stated for V
CC
= +3.3V and T
A
= +25°C.
(2) Specification is ensured by characterization.
(3) Specification is ensured by design.
(4) Input return loss is dependent on board design. The LMH0044 meets this specification on the SD044 evaluation board from 5 MHz to
1.5 GHz.
Connection Diagram
The exposed die attach pad is a negative electrical terminal for this device. It should be connected to the negative
power supply voltage.
