REF200AUE4

Current Regulation/Management Overview

The REF200AUE4 is a dual current source and sink integrated circuit manufactured by Texas Instruments. It provides two independent, stable output currents of 100 μA each. The device operates within an extended industrial temperature range from -25°C to +85°C. It is housed in an 8-pin Small Outline Integrated Circuit (SOIC) package with a width of 3.90 mm. The component is RoHS compliant and lead-free, ensuring environmental safety standards are met for modern electronic assemblies.

Current Regulation/Management Feature Summary

• Provides dual independent current sources and sinks for precise analog signal conditioning
• Operates reliably across the extended industrial temperature range of -25°C to +85°C
• Utilizes a compact 8-pin SOIC surface-mount package for efficient board space utilization

Current Regulation/Management Applications

• Precision analog sensor interface circuits requiring stable biasing
• Current mirror configurations in data acquisition systems
• Transimpedance amplifier biasing in photodiode detection applications

Current Regulation/Management Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status during procurement. Confirm the package designation matches the required 8-SOIC footprint for PCB layout compatibility. Ensure the operating temperature range meets the specific environmental requirements of the target application before finalizing orders.

Current Regulation/Management Selection Notes

Select this component when dual, matched current sources are required for precision analog applications. The fixed 100 μA output eliminates the need for external programming resistors, simplifying design complexity. Consider the SOIC-8 package constraints regarding thermal dissipation and pin pitch compatibility with existing manufacturing equipment.

Current Regulation/Management Part Context

This part belongs to the REF200 family of dual current source/sink devices from Texas Instruments. It succeeds earlier Burr-Brown designs under the TI portfolio. The device serves as a fundamental building block for creating stable reference currents in mixed-signal environments without requiring complex external feedback networks.

Current Regulation/Management Replacement Considerations

The REF200AU is the non-lead-free equivalent. Verify if the E4 suffix is strictly required for regulatory compliance. Other dual current sources may require external resistor adjustments for current setting.
