Notes
1. The distortion is measured with a bandwidth of 10 Hz to 30 kHz.
2. Frequency response externally fixed (input capacitors determine the low frequency roll-off).
3. The SE to BTL switch voltage level depends on the value of VP.
4. Noise output voltage measured with a bandwidth of 20 Hz to 20 kHz.
5. Noise output voltage is independent of Rs.
