Frequently Asked Questions
What is the output voltage accuracy of the REF1004I-1.2?
The REF1004I-1.2 provides a nominal 1.2 V output with an initial accuracy of 0.5%, corresponding to an output voltage range of 1.231 V to 1.239 V, making it suitable for precision analog signal conditioning and ADC reference applications.
What package does the REF1004I-1.2 use?
The REF1004I-1.2 is housed in an 8-pin Small Outline (SOIC-8 / R-PDSO-G8) surface-mount package, providing a compact footprint compatible with standard reflow soldering processes used in industrial and consumer electronic assemblies.
How does a two-terminal shunt voltage reference work?
A two-terminal shunt reference is connected in parallel with the load, and a series resistor sets the operating current. The device clamps the voltage at its rated value (1.2 V for the REF1004I-1.2), offering simple circuit integration with minimal external components and very low quiescent current draw.
What applications are best suited for the REF1004I-1.2?
The REF1004I-1.2 is well suited for portable instruments, ADC and DAC reference rails, battery-operated sensors, and comparator threshold circuits where a micropower 1.2 V precision reference reduces power consumption compared to bandgap references requiring higher supply voltages.
Is the REF1004I-1.2 RoHS compliant and lead-free?
Yes, the REF1004I-1.2 carries a Pb-free code of 'Yes' and meets JESD-609 classification e4, confirming RoHS compliance and suitability for environmentally regulated markets in Europe, Asia, and globally.
