Can the SGTL5000 be used like a regular DAC with regards to just staying at a certain voltage if desired? I would like to use it for modular synth control voltage (CV). Just want to make sure it's not necessary for it to constantly receive a stream of data. I'm not familiar with I2S.

I'm going to revisit my Teensy 3.x synth project, but this time around I'm going with an SSI2144 VCF and an analog VCA. So I'll need a bunch of control voltages in addition to the DCO from the Teensy.
