7.1 Application Information

The LMH6518 device is an excellent choice for applications that require a differential signal path and drive a differential, high-bandwidth analog-to-digital converter. The LMH6581 has 900 MHz of bandwidth and drives signals up to 1.8 VPP.

Typical applications for the LMH6518 include an oscilloscope AFE, gain control in a radio receiver, and a data-acquisition system.
