OPA2301: Voltage follower

Jingtai

Part Number: OPA2301
Other Parts Discussed in Thread: OPA355, TINA-TI

I have OPA2301AIDs and tried to make a voltage follower but WEBENCH reminds

In the datasheet there is G=1 but no Rf=0. It seems OPA2301 is not able to make a voltage follower. I also have OPA355QDIs and it is able to make a voltage follower according to its datasheet. Is may understanding correct?

OPA355 is not linked to WEBENCH.

Hi Jingtai,

The OPA2301 is unity gain stable, and will work as a voltage follower. WEBENCH just does not work for gains of less than 1.1V/V. I would recommend using TINA-TI instead to help with your design. It can be found under the tools and software tab on the OPA2301 page.

Best regards,

Sean
