Translating Existing Potentiometer
Circuits
Existing VCOM adjustment circuits using conventional
mechanical potentiometers can be translated into
MAX1512 circuits. Figures 3 and 4 show two common
adjustment circuits and their equivalent MAX1512 cir-
cuits.
Interface Enable/Disable (CE)
The MAX1512 control interface can be disabled to
reduce the V
DD
supply current. Connect CE to GND to
reduce the typical supply current from 32μA to 12μA.
Connect CE to V
DD
to enable the control interface.
