(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.}
