LMH6505 Datasheet (National Semiconductor)

LMH6505, Variable Gain Amplifier

The LMH6505 is a wideband DC coupled voltage controlled gain stage followed by a high-speed current feedback op amp 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.

Maximum gain is
