Two selectable banks of 14-channels allow fast hardware switching between two different gamma curves. The ISL24007 has 4 inputs (REFX_X) to set the reference voltages for the DACs. Two of these reference inputs set the range for the upper DACs and two of these reference inputs set the range for the lower DACs. The ISL24007 is configured and controlled via an I2C Interface. • 4 Static Buffers ISL24007 is available in a 38 Ld QFN package and is specified for operation over the -40°C to +85°C temperature range. • 1mA Digital Supply Current • 2 Banks of Volatile Memory for DACs • Fast Switching Time (<1µs) Between Output Banks • 4.5V to 19V Analog Supply Range • 2.25V to 3.6V Digital Supply Range • 11mA Analog Supply Current (Unloaded) • I2C Serial Interface • Pb-free (RoHS compliant) Applications • TFT-LCD Column Driver Reference Generator • General-Purpose Reference Voltage Generators Typical Application GAMMA VOLTAGES TFT-LCD PANEL TIMING CONTROL (TCON) COLUMN DRIVERS TFT-LCD SCREEN ISL24007 GAMMA BUFFER (COLUMN DRIVER DAC REFERENCE VOLTAGES) GATE DRIVERS DATA LINE SELECT LINE STORAGE CAPACITOR LC PIXEL TFT COMMON (VCOM) FIGURE 1.
