REF200AU/2K5E4

Current Regulation/Management Overview

The REF200AU/2K5E4 is a dual current source and sink integrated circuit manufactured by Texas Instruments. It provides two independent, stable output currents of 100µA each. The device operates within an input voltage range of 2.5V to 40V and maintains high accuracy with an initial tolerance of ±0.25%. It is housed in an 8-SOIC surface-mount package and supports an operating temperature range from -25°C to 85°C.

Current Regulation/Management Feature Summary

• Provides dual independent current sources and sinks for precise biasing applications
• Delivers stable 100µA output current with high initial accuracy
• Operates over a wide supply voltage range up to 40V

Current Regulation/Management Applications

• Precision analog signal conditioning circuits
• Biasing networks for operational amplifiers
• Current mirror configurations in sensor interfaces

Current Regulation/Management Procurement Notes

Verify the specific suffix E4 indicates lead-free compliance against the manufacturer's latest documentation. Confirm availability status as distribution data may indicate obsolescence or limited stock. Ensure the 8-SOIC package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Current Regulation/Management Selection Notes

Select this component when dual, matched current sources are required in a compact surface-mount format. The ±0.25% accuracy suits applications demanding tight current matching without external trimming. Consider the 8-SOIC package constraints and thermal dissipation capabilities relative to the ambient operating environment.

Current Regulation/Management Part Context

This part belongs to the REF200 family of precision current sources. The 'E4' suffix typically denotes environmental compliance, specifically lead-free manufacturing, consistent with Texas Instruments' product coding standards. It serves as a specialized PMIC solution for analog front-end designs requiring stable, low-current references.

Current Regulation/Management Replacement Considerations

The REF200AU/2K5 is listed as obsolete. Verify if REF200AU/2K5E4 is the direct active replacement or if alternative current source ICs from other manufacturers are required based on pin compatibility and electrical specifications.
