ISL24006 To request the full datasheet, please visit www.intersil.com/products/isl24006 March 9, 2006 14-Channel Programmable Switchable I2C TFT-LCD Reference Voltage Generator with Integrated 4-Channel Static Gamma Drivers Features 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. • Fast switch time (< 1µs) 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. • I2C interface • 14-channel programmable switchable • 4-channel static • Programmable with 20mV resolution • Digital supply 3.3V to 5V • Supply current of 32mA (without load) • Rail-to-Rail capability • Pb-free plus anneal available (RoHS compliant) Applications • TFT-LCD drive circuits • Reference voltage generators Pinout 32 OUT7 33 OUT6 34 OUT5 37 OUT2 OUT_REFU_H 1 Ordering Information TAPE & REEL PACKAGE PKG.
