LMH6502 - Linear-in-dB Variable Gain Amplifier

General Description

The LMH™6502 is a wideband DC coupled differential input voltage controlled gain stage followed by a high-speed current feedback Op Amp which can directly drive a low impedance load.

Gain adjustment range is more than 70dB for up to 10MHz.
