Description
The TSL1018 is composed of 18 + 1 channel
buffers which are used to buffer the reference
voltage for gamma correction in thin film transistor
(TFT) liquid crystal displays (LCD).
2
One "COM" amplifier is able to deliver high output
current value, up to ±150mA. Amplifiers A and B
feature positive single supply inputs for common
mode voltage, thus can be used for highest
gamma voltages. The amplifiers C to R inclusive,
and the COM amplifier, feature negative single
supply inputs and are dedicated to the lowest
gamma voltages.

1. PD is calculated with Tamb = 25°C, TJ = 150°C and RTHJA .
2. Human body model: a 100pF capacitor is charged to the specified voltage, then discharged through a
1.5kΩ resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
3. Machine model: a 200pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5Ω). This is done for all couples of
connected pin combinations while the other pins are floating.
4. Charged device model: all pins and package are charged together to the specified voltage and then
discharged directly to the ground through only one pin.

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 R have their input voltages in the rangeVSS 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 toVDD-1.5V.
