The 1/3, 1/2 and 2/3 VLCD voltage levels are buffered internally with an asymmetric output stage, as
shown in Figure A-5.
The switching matrix applies a capacitive load (LCD elements) to the buffer output. The charge excites the

behaves like a resistor. Simplified output voltage transients are shown in Figure A-6.. The shown
transients emphasize the spikes and the voltage recovery. They are not to scale. The buffer output
characteristic is shown in Figure A-7.. The resistive output characteristic is also valid if an output is forced
to GND or VLCD.
