a) 3- or 4-line display with 1/6 bias
b) 1- or 2-line display with 1/4 bias
Notes: 1. Potential differences between V
CC
and V1 and between V5 and V
EE
must be 0.4V or greater,
particularly for low-duty drive such as 1-line display.
2. When the internal operational amplifiers cannot fully drive the LCD panel used, an appropriate
capacitor must be inserted between each output of V1OUT to V5OUT and V
CC
to stabilize the
operational amplifier output.
