I'm trying to amplify a signal from a high impedance source (MCP4725, Sparkfun)
I need to find an buffer opamp that will be able to drive a 50 Ohm input impedance load.
Most opamps I've seen so far only drive a couple miliamps at most. To obtain the fullscale voltage range (0-5V), by Ohm's law V=IR I'd need something that is able to output 100mA. (Unless I am confused?)
If you guys could suggest opamps or workarounds I'd appreciate it!
