5. Normal input pins: P0 to P2, TEST1 to TEST5, SELC, SAIF, SAOF
6. Schmitt input pins: RES, SI, SICK, SIRQ, SRDY, OSC1
7. When the load capacitance is 50 pF.
8. The values for the oscillator capacitors C1 and C2 include the line capacitances.
9. The typical values for the current drain are for VDD = 5 V, room temperature, and typical samples.
10. Fs = 44.1 kHz and 20 kHz low-pass filter used. Measurement is with the external circuit structure and constants in the Sanyo evaluation board.
11. With the weight A filter used.
