Hi all,
I have just been introduced to LOG114[http://focus.ti.com/lit/ds/symlink/log114.pdf] and I am building a bioelectric signal amplifier. I am thinking of using the LOG114's A1,A2 and A3 as an instrumentation amplifier and the auxiliary op-amps A4 and A5 for filtering. But when I tried to modify the design for the above operation I am facing a lot of issues like frequency dependency over amplification and log conformity over change in frequency etc.
Has anyone tried using the LOG114 for such a use instead of the reference current input design ?
Thank you,
Cheers,
Kousik
