LMH6702: Reverse Isolation

Steve Widener

Part Number: LMH6702
Other Parts Discussed in Thread: TINA-TI

How much reverse isolation can this amplifier provide? That is, how much signal is seen at the input in the case where the output is driven. This is assuming a non-inverting gain of 2 circuit such as in Figure 24 of the datasheet.

Hi Steve,

I simulated this in TINA-TI and got differing reverse isolation depending on the exact configuration of the circuit. The termination resistor on the non inverting input makes a big difference, for example.

You can download the TINA-TI reference design from the web if you want to set up your own circuit.
