I'm planning to use the ADA4610 in unity gain configuration as a current buffer for a high precision (16-bit) DAC chip. The chip is labeled as being stable in the unity gain configuration. I currently have the chip configured like the image shown below. Practically speaking, should I be adding a capacitance in the loop or is this configuration truly stable? In addition, are there any best practices for this approach to current buffering?
If it's indeed unity-gain stable, you don't need to do anything beyond the voltage follower configuration you've shown above.
That said, you should note that the short circuit output current is 63 mA, so if you expect this thing to source/sink 200mA to drive a motor, it won't.
Also, with regard to the nature of the input, when powered with +/- 5 Volt rails, the chip will only function with inputs between -2.5V and +2.5V. So, if you're powering with a single sided supply, you can go nowhere near ground and expect the circuit to work! For that, you would need a chip with rail to rail inputs. Sometimes it even makes sense to use two -1 gain inverting op amps instead of a non-inverting follower, which let's you pin the inputs to a legal value, and you don't have to worry about your common mode input range.
At some level, there's no substitute for trying something to see if it works. Build the development time into your project. Modeling in LTSpice can also be a great timesaver.
