Overview
The REF1004C-1.2/2K5 is a micropower shunt voltage reference manufactured by Texas Instruments, featuring an initial accuracy of 0.3% and a temperature coefficient of 20 ppm/C. It provides a fixed output voltage of 1.2 V with a maximum shunt current of 20 mA and operates within a temperature range of -40°C to +85°C. The device is housed in an SOIC-8 surface-mount package and is supplied in a tape-and-reel format for automated assembly.
Feature Summary
- Micropower operation designed for low-current applications
- High precision with 0.3% initial accuracy
- Low temperature drift of 20 ppm/C
- Shunt reference topology
Applications
- Portable instrumentation requiring stable references
- Battery-powered measurement systems
- Data acquisition channels
- Precision analog front ends
Procurement Notes
Verify the specific suffix /2K5 corresponds to the tape-and-reel packaging configuration when ordering. Confirm that the C grade designation aligns with the required 0.3% initial accuracy specification for your design. Ensure the SOIC-8 footprint matches your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a 1.2 V reference is required with high precision and low power consumption. The 20 ppm/C temperature coefficient makes it suitable for environments with moderate thermal variations. Consider the shunt architecture requirements and ensure adequate heat dissipation within the 20 mA current limit.
Part Context
This part belongs to the REF1004 series of micropower voltage references from Texas Instruments. The series offers various output voltages and accuracy grades, providing designers with flexible options for precision analog circuits. The REF1004 family is known for its stability and low power characteristics in compact packages.
Replacement Considerations
The REF1004I-1.2 is a potential substitute offering similar specifications but with an industrial temperature range extension to +125°C. Verify pinout compatibility and electrical parameter alignment before substitution.
