ICL7663S
Generating a Temperature Compensated Display Drive Voltage
Temperature has an important effect in the variation of
threshold voltage in multiplexed LCD displays. As
temperature compensated display voltage, V_DISP, can be
generated using the ICL7663S. This is shown in Figure 11
temperature rises, the threshold voltage goes down. For
applications where the display temperature varies widely, a
