(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 power-down modes is measured without loading.

(5) Dynamic current is measured with active loading and the excercized output pins equal to ±2mA.
