(1)Dynamic performance is measured with an Audio Precision System Two Cascade or Cascade Plus test system.
(2)fsMIN = min (fsIN, fsOUT).
(3)fsMAX = max (fsIN, fsOUT).
(4)Power-supply current for the power-down modes is measured without loading.
(5)Dynamic power-supply current measurements are performed with 2mA active loads on the excercized outputs.
