Description
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. The TSL1014 is fully characterized and guaranteed over a wide industrial temperature range (-40 to +85C).

1. PD is calculated with Tamb = 25C, TJ = 150C and RTHJA = 85C/W for the TQFP48 package. 2. Human body model: A 100pF capacitor is charged to the specified voltage, then discharged through a 1.5k 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 < 5). 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.
