Product details

Fixed 2.048 V reference for precision analog rails

The MAX6018BEUR21+T from Analog Devices is a series voltage reference that delivers a fixed 2.048 V output with ±0.4% initial accuracy. It operates from a 2.25 V to 5.5 V input, drawing only 6 µA supply current, making it a fit for battery-powered instrumentation, portable medical gear, and industrial sensor interfaces where the reference rail must stay stable across temperature and line variations.

As a series reference, the MAX6018BEUR21+T regulates the output by adjusting its internal pass element — no external resistor is needed, and dropout voltage is low.

Frequently asked questions

What is the tolerance of MAX6018BEUR21+T?

Initial tolerance is ±0.4%, which sets the maximum output deviation at 25 °C to about ±8.2 mV. Temperature drift adds 50 ppm/°C, or roughly 0.1 mV per 10 °C.

Is the MAX6018BEUR21+T a series or shunt reference?

It is a series reference. The output is regulated by an internal pass element, so no external resistor is needed, and dropout voltage is low — unlike a shunt reference which requires a bias resistor and has a minimum operating current.
