Other Parts Discussed in Thread: TINA-TI,
We are currently using the Spice model (THS3491RGT TINA-TI Spice Model) provided by your website for simulation in circuit design using LTSpice.
For comparison with Figures 1 and 3 in the datasheet, simple non-inverting and inverting circuits were created.
And it was confirmed that the inverting circuit shows good flatness characteristics different from the datasheet at 100 MHz and above, but the non-inverting circuit has poor flatness characteristics from 100 MHz even at 5 V/V.
I would appreciate if you could give me some hints on this point.
