  • THS7530: THS7530 Noise Figure in AC Single-Ended Input Configuration

    Resolved
    Part Number: THS7530 Hello TI Forum, I have a question on the THS7530 noise figure. The data sheet noise figure references Figure 16, which uses a RF-transformer to generate the differential input. I would like to drive the THS7530 from a single-ended…

  • THS7530-Q1: Gain Error

    Resolved
    Part Number: THS7530-Q1 Hi, Data sheet of THS7530-Q1 page7 Please tell me how to look at Figure2. When VG+ = 0V　, Gain is 11.6dB (typ) When VG+ = 0.9V, Gain is 46.5db (typ) This is described in datasheet page5. This value is a reference value, I understand…

  • THS7530: Driving the Gain Setting Input In Double Ended supply

    TI Thinks Resolved
    Part Number: THS7530 I would like to use this part the Vcom at 0V. I'm using a +/-2V power supply. What will be the VG- Referenced to? Will the voltage range still be 0 to 0.9V in this case? Thank you,

  • THS7530: CMRR curve, data sheet figure 12

    Resolved
    Part Number: THS7530 I don't understand the sign of the CMRR curve in figure 12 of the data sheet. I believe that the CMRR definition is the ratio of common mode voltage applied to both inputs to generate a given output voltage A, divided by the…
