1. Test Condition: Common Mode Offset Control disabled (CR.CMOC = 0). Alternative Upsampling Ratio disabled
2. Performance numbers for dynamic range, SNR, and THD performance are very dependent on the application and circuit
3. These values are based on simulation and characterization of other AVR microcontrollers manufactured in the same pro-

board design. Since the design has 0dB Power Supply Rejection Ratio (PSRR), noise on the IO power supply will couple
directly through to the output and be present in the audio signal. To get the best performance one should reduce toggling of
other IO pins as much as possible and make sure the device has sufficient decoupling on the IO supply pins.
