Note that:

● Amplifiers A & B have their input voltages in the range VSS+1.5V to VDD. This is why

they must be used for high level gamma correction voltages.

● Amplifiers C to T have their input voltages in the range VSS to VDD-1.5V. This is why

they must be used for medium-to-low level gamma correction voltages.

● Amplifier COM has its input voltage range from VSS to VDD-1.5V.
