Voltage References

 

End of Life (EOL) Notice »

 

Silicon Labs' voltage reference devices are precision 3-terminal, series-mode 2.5-V offering a pin-for-pin, identical compatibility to the MAX6025 voltage reference with improved electrical performance. The voltage reference devices consume only 31 µA of supply current at no-load, exhibit an initial output voltage accuracy of less than 0.08%, and a low output voltage temperature coefficient of 7 ppm/°C. In addition, the output stage is stable for all capacitive loads to 2200 pF and is capable of sinking and sourcing load currents up to 500 µA.

Since the devices are series-mode voltage references, its supply current is not affected by changes in the applied supply voltage unlike two-terminal shunt-mode references that require an external resistor. Their small form factor and low supply current operation all combine to make it an ideal choice in low-power, precision applications.

The voltage reference devices are fully specified over the -40 °C to +85 °C temperature range and is available in a 3-pin SOT23 package.
