Can somebody list some good op-amps for amplifying 0-15mV to 0-5V ?

Thanks

 

Sure, download the TI linear data book. Almost any op-amp can do that. How about being a little more specific about what you need.

 

I am trying to amplify voltage output from a pyranometer, measures sunlight irradiance in 5-20mV and use it for data logging purposes. I have a cRIO with AI +-10V IO.

 

OK, so you need a low speed well behaved precision op-amp. What is your available power supply voltage(s)? Are there any voltage offsets in your input voltage? Do you need more than one op-amp per package? Filtering? Output impedance of your sensor, high or low? Input impedance of your I/O channel?

 

Also, does the sensor output really go down to 0.0V, or just to a really low (but non-zero) voltage? If the latter, you might be able to go with a "rail-to-rail" opamp and require only one power supply.
