LMH6505 is a wideband, low power, linear-in-dB, variable gain amplifier from Texas Instruments. This device uses a voltage controlled gain stage followed by a high-speed current feedback op amp that can directly drive a low impedance load. LMH6505's gain adjustment range is 80 dB for up to 10 MHz.
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, accomplished by varying the gain control input voltage (Vg). Maximum gain is set by external components, and the gain can be reduced all the way to cut-off.
