I've been wanting to make Buffered Voltage Bias circuit described on this page: Learn: Electricity Monitoring — OpenEnergyMonitor 0.0.1 documentation
The problem I have is that the only LMV321s i can find come in a tiny package that i'm not able to use and with limited electronic knowledge i'm struggling to find an equivalent that i can, ie a DIP package. Here's a link to the data sheet for the LMV321; http://www.ti.com/lit/ds/symlink/lmv324.pdf. I'm not too bothered if i end up with one multiple channels (that i dont use) as long as it is like for like in it's function. Any help would be greatly appreciated. 
An LM358 or LM324 would work. The LMV series are lower voltage versions, but the LM324 works down to 3V single supply. The output will only go to 1.5V below V+, but that's fine, in this case.

I use these to make SOICs into DIPs: soic 8 adapter pcb for sale | eBay
Hi, thanks very much for the advice. I had not seen the soic 8 adapter adapters before, I'll have to try soldering to one of those in the future. I've got fat fingers so they're always gonna be a problem though
I had seen the LM358 when i was searching and had (kinda educated) guessed it could be used as a replacement. Thanks again for the advice
