Frequently Asked Questions
What output voltage does the REF1004C-2.5G4 provide, and how accurate is it across temperature?
The REF1004C-2.5G4 delivers a fixed 2.5 V shunt reference voltage with a low temperature coefficient, ensuring the output remains stable across the full industrial temperature range from -40°C to 85°C for precision analog circuits.
In which measurement or calibration scenarios does the REF1004C-2.5G4 offer an advantage over a bandgap reference?
As a 2.5 V shunt reference, the REF1004C-2.5G4 suits two-terminal topologies where the reference cathode is biased by a series resistor, ideal for ADC reference inputs and calibration circuits requiring a stable 2.5 V without additional regulator ICs.
How many pins does the REF1004C-2.5G4 have, and does the 8-pin SOIC package allow for easy decoupling?
The REF1004C-2.5G4 uses an 8-pin SOIC package, providing ample PCB space to place 100 nF decoupling capacitors close to the reference pins, which reduces noise and improves transient response for sensitive 2.5 V reference nodes.
Can the REF1004C-2.5G4 be used in battery-powered portable instruments that operate down to -40°C?
Yes, the REF1004C-2.5G4 supports operation from -40°C to 85°C. Its low quiescent current shunt topology minimizes power consumption in battery-powered handheld meters and field instruments needing a reliable 2.5 V reference throughout the industrial temperature range.
