How much load does DAC61416's output amplifier work?
The document of DAC60508 describes "Each buffer amplifier is capable of driving a load of 2 kΩ in parallel with 10nF to GND."
Thank you!

Hi,
DAC61416's output drive capability is 25mA with a headroom of 1.5V from supplies.
What this means is that, lets say you are operating with +/-10V output range, and if DAC needs to drive 400 ohms (meaning 25mA current), you need to provide min supply of +/-11.5V.
Headroom requirements will come down, when you are drawing less current from the device. 2K load, you dont need much headroom, even with +/-10.3V supply you should be fine. Have a look at datasheet page number 17, figure 25 & 26
