LMH6678 Description

The LMH6678 is a low power 2-channel differential output driver utilizing dual current feedback op amps with a fixed gain of AV = +5.4. The LMH6678 utilizes high integration with low power consumption to provide 580 mW at 19.8 dBm line output. The LMH6678 can also be put into a listen mode to maintain the termination for receive signals with 100 mW/Ch power dissipation.
