The ISL24005 is a 14-Channel programmable reference voltage generator with four channels of static gamma drivers and programmable Vcom calibrator integrated, for a complete 18-Channel total gamma solution for TFT-LCD displays.
The ISL24005 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.
ISL24005 includes an I2C interface for programming the offset values.
ISL24005 is available in the 32 Ld Thin QFN package and is specified for operation over the -40°C to +85°C temperature range.
