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.
