Sine Wave Input Signal and Sine Wave Power Ring Signal Output
(continued)
It is recommended that the input level at RING
IN
be adjusted so that the power ring signal at tip and ring is just at
the edge or slightly clipping. This gives maximum power transfer with minimal distortion of the sine wave. The tip
side will saturate at a nominal 1 V above ground. The ring side will saturate at a nominal 3 V above battery. The
input circuit for a sine wave along with waveforms to illustrate the tip and ring saturation is shown in Figure 12.

Figure 12. RING
IN
Operation
The point at which clipping of the power ring signal begins at tip and ring is a function of the battery voltage, the
input capacitor at RING
IN
, and the input signal at RING
IN
and Vcc. Typical characteristic conditions showing the
onset of clipping are given below.
