LMH6502 Wideband, Low Power, Linear-in-dB Variable Gain Amplifier
General Description
The LMHTM6502 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 300mW with a speed of 130MHz. Output referred DC offset voltage is less than 350mV over the entire gain control voltage range. Device-to-device Gain matching is within ± 0.6dB at maximum gain. Furthermore, gain at any VG is tested and the tolerance is guaranteed. The output current feedback Op Amp allows high frequency large signals (Slew Rate = 1800V/µs) and can also drive heavy load current (75mA). Differential inputs allow common mode rejection in low level amplification
