The TSL1014 is composed of 14 + 1 channel
buffers which are used to buffer the reference
voltage for gamma correction in thin film transistor
(TFT) liquid crystal displays (LCD).

One "COM" amplifier is able to deliver high output
current value, up to ±100mA. Amplifiers A and B
feature positive single supply inputs for common
mode voltage behavior. The amplifiers C to N
inclusive, and the COM amplifier, feature negative
single-supply inputs and are dedicated to the
highest and lowest gamma voltages.

1. PD is calculated with Tamb = 25°C, TJ = 150°C and RTHJA = 85°C/W for the TQFP48 package.
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.

Note that:
●
Amplifiers A & B have their input voltage in the range VSS+1.5V to VDD. This is why
they must be used for high level gamma correction voltages.
●
Amplifiers C to N have their input voltage 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.
