ad420 DC level

Hi,

 

I need to drive a laser at ~12-14 mA DC, the laser has an impedance of ~163 ohms. The maximum allowed drift is +/-0.6 mA.

 

We have been looking at ad420, but I have some questions to insure the it is suitable for our application.

 

  • Is the output impedance of it is suitable for my use?
  • If not can you recommend an op amp that can lower the output impedance?
  • Is it able to hold a constant DC level over long over a long period of time

 

Hope you can help
