NOTES:

1. See APPENDIX D for parameter definition and measurement technique.

2. Values are guaranteed by characterization and sample testing but are not 100% production tested.

3. Frequency value obtained by multiplying by the DAC sampling rate.

4. DC current only. If dynamic loading exists, the voltage reference output must be buffered to prevent

DAC performance degradation.

5. The USB audio extension unit control selector OUTPUT_DOUBLE is used to control the full scale

DAC channel output level as specified. For 3V operation, the property must be set to FALSE. DAC

signal range saturation will occur if operating at 3V with a property setting of TRUE. For 5V

operation the property can be set to TRUE or FALSE. This property has no effect on the full–scale

output level of the AUX and MIC analog signal channels before the output mixer.

6. Voltages referenced to ground.

7. Input impedance is a function of the mixer attenuation setting for the analog input channel. The min

value is at the +30 dB setting, the nominal value is at the 0 dB setting, and the max value is at the –32

dB setting.

8. The minimum load impedance the LOUT and ROUT output amplifiers are designed to drive.
