precision amplifier circuit

[thiam]

Hi,
i need a guideline to construct a precision amplifier circuit to a motor driver(OPA 541). my input voltage is from -5V to 5V whic from PIC18F4331. Anyone can help me?? pls reply thanks.

You would need to specify a whole lot more than that to come up with a circuit.

"Precision" means what?

What are you trying to do exactly?

Since i using PIC18F4331, i have been told that its output current is not constant. as i know, a precision amplifier can constant the current.

i have question about the PIC18F4331
Do the chip have 5 to -5 output? i mean the chip have negative output signal?

You're still making no sense at all - tell us EXACTLY what you want to do, not how you imagine it needs to be done.

As it's only fed from a +ve 5V supply, obviously not.
