Even in the event of large power supply variations, this REF198GRUZ voltage reference power management device from Analog Devices can produce and maintain a precise DC voltage. By working with a maximum input voltage of 18 V, this is the best way to control the power in your circuit. With an output that has a voltage of 4.096 V, this is power management at its best. It has an initial accuracy of 2mV. This voltage reference circuit supports series topology. At a load regulation of 8ppm/mA and line regulation of 8ppm/V a constant current can be produced at the output of your circuit. In order to ensure parts aren't damaged by bulk packaging, this product comes in tube packaging to add a little more protection by storing the loose parts in an outer tube. This voltage reference circuit has an operating temperature range of -40 °C to 85 °C. It runs with a maximum temperature coefficient of 25ppm/°C.
