Gain adjustment range is more than 70d B for up to 10MHz. Maximum gain is set by external ponents and the gain can be reduced all the way to cut-off. Power consumption is 370m W with a speed of 135MHz . Output referred DC offset voltage is less than 350m V over the entire gain control voltage range. Device-todevice Gain matching is within 0.7d B at maximum gain. Furthermore, gain at any VG is tested and the tolerance is ensured. The output current feedback Op Amp allows high frequency large signals (Slew Rate = 1800V/μs) and can also drive heavy load current (75m A). Differential inputs allow mon mode rejection in low level amplification or in applications where signals are carried over relatively long wires. For single ended operation, the unused input can easily be tied to ground (or to a virtual half-supply in single supply application). Inverting or non-inverting gains could be obtained by choosing one input polarity or the other. To further increase versatility when used in a single supply application, gain control range is set to be...
