Excuse me, the output current of OP279 is a fixed value?Or does it change with the input voltage?I want to design a circuit ， 0-10v to 0-50ma, what chip should I choose? Thank you!
No, the output current is not a fixed value. The actual output current of the amplifier will depend on what load you have. On a +/-5V supply, I see a short circuit current limit of +/-50mA though. If you actually need 50mA out, the OP279 would not be a good choice.
What is your application? What will your input source be? What is the bandwidth that you require and do you have limitations on your supplies? Let me know so I can find the best solution for you.
