TLV2186: FilterPro

SEUNG IN LEE

Part Number: TLV2186

I designed a sallen key topology 2nd filter by FilterPro.

then FilterPro shows me this conclusion

and there is no macro file in TINA TI.

so i downloaded tsm file and insert that( INSERT -> MACRO -> TLV2786.tsm)

and i designed it samely

but the frequency response is wrong, what happened?

and what can i do?

ah.. there is error from 3rd picture.

the content of 3rd picture is that there was absolutely different frequency response, no 20dB start , -90 dB start , phase response is wrong also

Your file did not insert, use the little paperclip symbol to attach a TINA file,

Here is the Tina reference design for the TLV2186 (not sure why you went to the TLV2786 above?)

As for your sim mismatch, what are your filter targets
