MAX9697 12-Channel Programmabl
max9697 12-channel programmable gamma reference system
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.
