THS6022: Design a follower with high input impedance

Part Number: THS6022

Hi，

    I have stocked surfficient THS6022. Thus I would like to use the THS6022 to design a gain-1 follower with high input impedance. Is there any reference design can provide me? I would very appreciate.

    Hi,

    this is very simple. Omit in figure 2 of datasheet Rg and choose Rf according to table 1 of datasheet. In this table there's a little typo: The left supply voltage is correct (Vcc=+/-15V), but the right supply voltage must be Vcc=+/-5V.

    If you want to drive a (moderate!) capacitive load, use figure 55 of datasheet. And if you intend to drive transmission lines, see figure 65.
