  • LMP8646: Understanding about Gain

    TI Thinks Resolved
    Part Number: LMP8646 Hi, I'm confused when see the Figure 6 and Figure 7 in the LMP8646's datasheet. (Gain vs. Frequency) For example in the Figure 7: (1) RG (black line) is 50k, so Gain = 10 = 10dB but in the plot, Gain is about 6dB (2) Why Gain…
