NOTES:

2. TA = 25oC, VAA = VDD = 5.0V

3. Guaranteed but not production tested.

4. Based on 1kHz, Full scale analog tone input; Measurement Bandwidth is 20 to 20kHz, A-weighted.

5. DAC’s driven with 1kHz, Full Scale PCM Sine Wave, output measurement bandwidth is 20 to 20kHz, A-weighted.

6. Test performed with CL = 40pF, IOL = 4mA, IOH = -4mA. Input reference level is 1.5V for all inputs. VIH = 3.0V, VIL = 0V.

7. This is measured relative to a nominal output level.
