The MAX9697 12-channel programmable gamma reference system provides 12 programmable reference voltages with 10-bit resolution. These voltages can be used for gamma correction in TFT-LCD displays, as a VCOM reference, or as sources for level shifter inputs. Each reference voltage features a 10-bit digital-to-analog converter (DAC) and buffer with high peak current to reduce the recovery time of the output voltages when critical levels and patterns are displayed.
An adjustable, low-dropout linear regulator (LDO) further improves the stability and accuracy of the DAC outputs by creating the DAC reference. The MAX9697's integrated gate-driver output controls an external p-channel FET to slowly turn on the linear regulator so that the reference voltages ramp up in a controlled manner.
The MAX9697 has a serial peripheral interface (SPI™) bus for programming the reference voltages. The device also has a current-sense comparator to detect an abnormally high supply current in other areas of the application circuit.
The MAX9697 is available in a 28-pin TQFN package and is specified for operation over the -40°C to +125°C temperature range.
