TOTAL HARMONIC DISTORTION (FIGURE 4)
Use the lower distortion oscillator for this measurement
because distortion of the TK15323 is very low.
1) Pin 5 is in the open condition, or high level.
2) Connect a distortion analyzer to Pin 3.
3) Input the sine wave (1 kHz, 1 Vrms) to Pin 4.
4) Measure the distortion of Pin 3. This value is the
