LMH6552: Gain obtained by TINA simulation

Part Number: LMH6552

Hi team，

I use the values in table 1 to emulate the figure 45 circuit, but the output gain is inconsistent with the values in table 1.What might be the cause

    Hi Amy,

    the gain could be referred to the node "Av,Rin", not to the input signal. Keep in mind that the input signal is divided by a factor of two because of Rs, Rt and Rin. And -6dB + 6dB = 0dB, what the simulation shows.
