® ISL24006 Data Sheet September 9, 2005 FN6110.1 14-Channel Programmable Switchable I2C TFT-LCD Reference Voltage Generator with Integrated 4-Channel Static Gamma Drivers The ISL24006 is a 14-channel programmable switchable reference voltage generator with four channels of static gamma drivers integrated, for a complete 18-channel total gamma solution for TFT-LCD displays. The 14-channel programmable switchable configuration allows switching between two gamma curves. The ISL24006 is divided into two banks of seven generators: one designed to cover the range from VREFL_L to VREFL_H; the remaining seven channels covering the range from VREFU_L to VREFU_H. Each bank has its own separate high and low reference inputs, with integrated buffers (four static gamma drivers) to drive the column driver internal DAC resistor string to within 0.2V from the top and bottom rails. An output MUX is used to switch between the two curves in less than 1µs. Switching is controlled using an external select pin. ISL24006 includes an I2C interface for programming the offset values.
