Description

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.

The ISL24008 is divided into two banks of seven generators: one designed to cover the range from V_{REFL_L} to V_{REFL_H}; the remaining seven channels covering the range from V_{REFU_L} to V_{REFU_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.

ISL24008 includes an SPI interface for programming the offset values.

ISL24008 is available in the 32 Ld TQFN package and is specified for operation over the -40°C to +85°C temperature range.
