LMH6502 - National Semiconductor

LMH6502 Wideband / Low Power / Linear-in-dB Variable Gain Amplifier

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. Maximum gain is set by external components and the gain can be reduced all the way to cut-off. Power consumption is 300m.
