LMH6505 Datasheet Variable Gain Amplifier

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: .. LMH6505 Wideband, Low Power, Linear-in-dB, Variable Gain Amplifier January 2006 LMH6505 Wideband, Low Power, Linear-in-dB, Variable Gain.

General Description

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 acplished by varying the gain control input voltage, VG.

Maximum gain is set by external ponents, and the gain can be reduced all the way to cut-off.
