2 Audio performance parameters may degrade outside the range of 0 to 70 degrees C. Internal oscillator speed will vary with temperature
3 Device will operate down to 0.9V but with degraded system specifications
4 DSP core active; single channel; direct digital output enabled and connected to 100kΩ resistance
