LMH6505 - Variable Gain Amplifier

General Description

The LMH6505 is a wideband DC coupled voltage controlled gain stage followed by a high speed current feedback operational amplifier which can directly drive a low impedance load.

The gain adjustment range is 80 dB for up to 10 MHz which is accomplished by varying the gain control input voltage, VG.
