I want to know how to use an OPA820 op-amp. I’m trying to increase the current coming out of my DAQ system. It says this op-amp outputs 110 mA, but I’m not getting that. I’m only getting 20 milliamps. I’m supplying the op-amp with 5V and 50 mA. Can anyone assist me with this, please?

Hello abigailsimms23 ,

Thank you for contacting Digi-Key TechForum. The output current will depend on the resistance of the load, along with how you have the circuit wired and other factors such as the signals going into the amp. Would you be able to provide a schematic of how the device is wired and provide more detail of the signals driving the amplifier?
