*) Specifications subject to change without notice.

Note 8: Filter is connected as low pass and set for 20 KHz cut-off frequency.

Note 9: Output signal is 3dB below clipping point.

Note 10: Output signal is 3dB below passband level, which is 3dB below clipping point. In general, this is

worst case condition.

Note 11: Distortion is predominantly second harmonic.

Note 12: Sinewave is not clipped by first stage.
