CURRENT MODE OUTPUT
Figure 31 Video Buffer with 0dB Gain
Figure 32 Video Buffer with 6dB Gain
The current mode output employed by the WM8941 video buffer allows VBVDD to operate at lower
voltages than voltage mode video buffers, reducing power consumption, while the use of a current
reference resistor close to the WM8941 ensures that the signal swing seen at the output of the buffer
will be the same as that at the connection to the receiving equipment (e.g. a TV), providing excellent
signal reproduction.
Current mode output also provides inherent protection against short circuits during jack insertion and
removal.
