INVERTING NONINVERTING The THS3001 EVM is equipped with both noninverting and inverting inputs. The noninverting input is set for a gain of 2 and the inverting input is set for a gain of 1. Each input is terminated with a 50- resistor to provide correct line impedance matching (Figure 1–3 for original version and Figure 1–4 for Rev. -

Rev. A Noninverting Even though the THS3001 is a current-feedback amplifier, the gain of the EVM can easily be changed to support a particular application by simply changing the ratio of resistors R1, R4, and R5 (R1, R2, and R4 for Rev. A) as described... -

7) Verify the output signal on the oscilloscope. Note: The signal shown on an oscilloscope with a 50- input impedance will ½ the actual THS3001 amplifier IC output voltage. This is due to the voltage division between the output resistor (R2) and the oscilloscope input impedance. -
