SPX1004N-L-2-5

Overview

The SPX1004N-L-2.5 is a two-terminal voltage reference manufactured by Sipex, providing a nominal output of 2.5V. It utilizes bipolar technology and is housed in an SOIC-8 package (PDSO8). The device operates within a temperature range extending up to 70°C. Key electrical specifications include a maximum dynamic impedance of 0.6 Ω and a low operating current ranging from 10µA to 20mA. Initial voltage tolerance is specified at ±20mV for the 2.5V variant.

Feature Summary

• Provides stable two-terminal voltage reference functionality
• Features low dynamic impedance for consistent performance
• Supports wide operating current range from micropower to higher loads

Applications

• A/D and D/A converter references
• Reference source for 5V systems
• Digital voltmeter circuits

Procurement Notes

Verify the specific suffix 'N' against official Sipex documentation to confirm package type and temperature grade. Ensure compatibility with lead-free requirements if applicable. Confirm that the SOIC-8 pinout matches the target design schematic before procurement.

Selection Notes

Select this component when a fixed 2.5V reference is required with low power consumption. Consider the SOIC-8 footprint constraints and the 70°C upper temperature limit. Compare initial tolerance requirements against the ±20mV specification to ensure accuracy needs are met.

Part Context

This part belongs to the SPX1004 series of micropower voltage references. It serves as a direct replacement for legacy components such as the LT1004, LM1004, and AS1004. The series offers both 1.2V and 2.5V options in various packages.

Replacement Considerations

Official datasheets identify the LT1004, LM1004, and AS1004 as direct replacements or equivalents.
