Notes to the characteristics

1. The substrate voltage must be lower than or to equal than the lowest supply voltage.

2. Output level tracks linearly with both the clock frequency and the reference voltage (Vref L or Vref R).

3. Device measured in differential mode with external components as shown in Fig.5.

4. Measured with a one-bit data signal generated by the SAA7350 from an 8 fs (352.8 kHz), 20-bit, 1 kHz digital

sinewave. Measured over a 20 Hz to 20 kHz bandwidth.

5. Measured with a one-bit data signal generated by the SAA7350 from an 8 fs (352.8 kHz), 20-bit, 20 Hz to 20 kHz

digital sinewave. Measured over a 20 Hz to 20 kHz bandwidth.

6. Power supply rejection ratio measured with fripple = 1 kHz and vripple = 100 mV.

7. The specified signal-to-noise ratio includes noise introduced by the application components as shown in Fig.5.
