I want to create a high precision voltage source, +/- 2.5 volts with < 1 microvolt steps. To do this I need a high bit depth DAC, 26+ bit. But the DACs that have that high of a bit depth are usually labeled as 'audio' and have filters. Can I output static DC levels? I assume if there is only a low pass filter then I am able to do this. But a lot of these have DSP filters and I do not know anything about DSP.
Thank you in advance.
