5. OPERATION OF OUTPUT BUFFER
The output buffer consists of an operational amplifier circuit that does not perform precharge operation. Therefore,
driver output current I
VOH1/2
is the charging current to the LCD, and I
VOL1/2
is the discharging current
.
The chip has the driving capability to charge or discharge a liquid load with C
