DISPLAY APPLICATIONS

Figure 1. VCOM adjustment application assuming that a +5V supply is available. In this case, VDD and VLOGIC would be tied together.

Figure 2. This circuit demonstrates the flexibility of a VLOGIC pin when a separate supply is not available for VDD. VDD can be tapped off

the +14.4V where it is resistor divided down to approximately ~5V. VLOGIC 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 VLOGIC, and VDD will only draw microamps of supply current used to

bias up the internal switches in the digital potentiometer’s internal resistor string.
