ISL24008 To request the full datasheet, please visit www.intersil.com/products/isl24008 Data Sheet November 1, 2010 FN6197.1 14-Channel Programmable SPI TFT-LCD Reference Voltage Generator with Integrated 4-Channel Static Gamma Drivers and Integrated Programmable VCOM Calibrator Features The ISL24008 is a 14-Channel programmable reference voltage generator with four channels of static gamma drivers integrated, for a complete 18-Channel total gamma solution for TFT-LCD displays. • Programmable with 20mV Resolution The ISL24008 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. • SPI Interface ISL24008 includes an SPI interface for programming the offset values.
