VBIAS SUPPLY
The VBIAS supply operates from 2.6V to 6.6V. It is the gate
drive voltage for all of the output N-channel MOSFETs. This
allows the output peak current sink to be set by varying the
V voltage. A higher V voltage will increase the current

sinking capability.
If large peak currents are not required, VDD and VBIAS can be
connected to the same power supply, provided they are both
within the operating range. The operating VDD range is 2.0V
to 5.5V. A plot showing the typical characteristics of I vs
SINK
VBIAS is shown below.
