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.
