Figure 1. V
COM
adjustment application assuming that a +5V supply is available. In this case, V
DD
and V
LOGIC
would be tied together.
Figure 2. This circuit demonstrates the flexibility of a V
LOGIC
pin when a separate supply is not available for V
DD
. V
DD
can be tapped off
the +14.4V where it is resistor divided down to approximately ~5V. V
LOGIC
can then be taken off the same supply that powers the MCU’s
logic levels. Now, the 35 mA programming current will be drawn by V
LOGIC
, and V
DD
will only draw microamps of supply current used to
bias up the internal switches in the digital potentiometer’s internal resistor string.
