Low-Power Programmable Gamma Buffers

Active: In Production.

The MAX9599A provides multiple programmable reference voltages for gamma correction in TFT LCDs. Each gamma output comprises a 10-bit digital-to-analog converter (DAC) and high current buffer, which reduces the recovery time of the output voltages when critical levels and patterns are displayed. A precision-programmable internal reference sets the full-scale voltage of the DACs.

The gamma output voltages and the programmable reference, programmed digitally through the 1MHz (fast mode plus) I²C interface.
