Quiescent current is 135 µA, low enough that the reference does not dominate the power budget in a battery-powered design. ## Noise performance for precision loops Noise is specified at 39 µVp-p from 0.1 Hz to 10 Hz and 57 µVrms from 10 Hz to 10 kHz. That is clean enough for a 12-bit or 14-bit SAR ADC without an external filter cap, though a 0.1 µF ceramic on the output does not hurt. For a 16-bit system you might want a lower-noise reference, but for the majority of industrial and instrumentation loops this is in the sweet spot.
