Hi, Ioannis

Have a look here ...

http://pdf1.alldatasheet.com/datashe.../SSM-2110.html

nice, but may be difficult to find ... and expensive.

but worth it.

I've also found an AOP and linearizing diodes solution, but won't give the dynamics and precision you look for ...

Thanks Alain. I 'll stick to NE604, although more expensive than CA3089, because is operating on 5V directly and is great!

I was wondering what AOP was! Thanks!

You can use the SA605 (is more newer model than NE604) , and this is operating on 5-8V.

Thanks Nik. And a bit cheaper too!
