7. When the load capacitance is 50 pF
8. The values for the oscillator capacitors C1 and C2 include the wiring capacitances.
9. The value for the current drain is a typical value for V_DD = 5 V, room temperature, and a typical sample.
10. With weight A filter present, with Fs = 44.1 kHz, and tested in the Sanyo evaluation board.
11. Varies with the values of the external components. The listed value is for the circuit structure and values shown in Figure 9 in the Sanyo evaluation
board.
