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 +85° C). 7 x 7mm TQFP48 VSS VDD 13 14 15 16 17 18 19 20 21 22 23 24 48 44 43 42 41 40 39 38 3746 45 A B C D E F G Com N M L K J I H VDD VSS VSSVDD VSSVDD VSS VDD VSSVDD VSS VDD 13 14 15 16 17 18 19 20 21 22 23 24 48 44 43 42 41 40 39 38 3746 45 A B C D E F G Com N M L K J I H VDD VSS VSSVDD VSSVDD VSS VDD VSSVDD Pin connections (top view)
1 Absolute maximum ratings and operating conditions
Table 1. Absolute maximum ratings
- P D is calculated with Tamb = 25° C, TJ = 150° C and RTHJA = 85° C/W for the TQFP48 package.
- Human body model: a 100 pF capacit or is charged to the specified voltage, then discharged through a
while the other pins are floating.
- Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
connected pin combinations while the other pins are floating.
- Charged device model: all pins and package are ch arged together to the specified voltage and then
discharged directly to the ground through only one pin. Table 2. Operating conditions
2 Typical application schematics
Figure 1. A typical application schematic for the TSL1014
- Amplifiers A & B have their input voltage in the range VSS+1.5 V 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-1.5 V. 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-1.5 V. COM A B C D E F G H I J K L M N VSS VDD R10 R11 R12 R13 R14 Gnd Gnd Com Ref.

4 Package information
In order to meet environmental requirements, STMicroelectronics offers these devices in ECOPACK® packages. These packages have a lead-free second level interconnect. The category of second level interconnect is marked on the package and on the inner box label, in compliance with JEDEC Standard JESD97. The maximum ratings related to soldering conditions are also marked on the inner box label. ECOPACK is an STMicroelectronics trademark. ECOPACK specifications are available at: www.st.com
