you can also use maxim's chips max471 or max472
you can use national's chip LM3812 and family

the intrusive resistance is only some milli-ohms

hope this helps.

Hello!

I'd like to tell you that in MAX471 and 472 you will have a lot of linearity problems in lower 10% of meassuring range.

Regards!
