SPX1004AS2-L-1-2

Overview

The SPX1004AS2-L-1-2 is a two-terminal voltage reference manufactured by Sipex, featuring a nominal output voltage of 1.235V. It operates within a bipolar configuration and utilizes an SOIC-8 (PDSO8) lead-free package with eight terminals. The device provides one functional output and is designed for applications requiring stable voltage references.

Feature Summary

• Provides a precise 1.235V reference output
• Operates with low dynamic impedance
• Supports wide operating current range from 10µA to 20mA

Applications

• A/D and D/A Reference
• Reference for 5V Systems
• Digital Voltmeter

Procurement Notes

Verify the specific suffix 'L' indicates lead-free compliance and 'S2' denotes the SOIC-8 package variant. Confirm that the '1-2' designation corresponds to the 1.235V output version. Ensure the component matches the original Sipex specifications rather than generic equivalents.

Selection Notes

Select this component when a micropower voltage reference with high initial accuracy is required. It serves as a direct replacement for LT1004, LM1004, and AS1004 devices. Consider its low operating current and stability for precision analog circuits.
