LM334 MWC

Current Regulation/Management Overview

The LM334 MWC is a three-terminal adjustable current source from the LM134/LM234/LM334 family, manufactured by Texas Instruments. It operates within an input voltage range of 1V to 40V and supports programmable output currents from 1µA to 10mA. The device features ±6% initial accuracy and operates across a temperature range of 0°C to 70°C. It is supplied in wafer form for custom packaging integration.

Current Regulation/Management Feature Summary

• Three-terminal adjustable current source architecture
• Wide dynamic voltage range operation
• Current determination via external resistor

Current Regulation/Management Applications

• Custom integrated circuit manufacturing
• Wafer-level testing and characterization
• OEM specific power management module development

Current Regulation/Management Procurement Notes

Verify that the procurement channel provides genuine Texas Instruments wafers. Confirm the specific wafer lot and processing status align with project requirements. Ensure handling procedures for bare silicon are strictly followed to prevent electrostatic discharge damage during storage and integration.

Current Regulation/Management Selection Notes

Select this component when integrating current source functionality directly into custom ASIC or hybrid designs. It is suitable for applications requiring precise current regulation without discrete packaging constraints. Evaluate thermal management strategies for wafer-level integration to maintain performance within the specified operating temperature range.

Current Regulation/Management Part Context

This part belongs to the LM334 series of precision current sources. Unlike packaged variants such as the LM334SM or LM334Z, the MWC suffix indicates a wafer sale format. This allows manufacturers to dice and package the die according to specific application needs rather than using standard off-the-shelf packages.

Current Regulation/Management Replacement Considerations

Direct substitutes include other LM334 series wafers if available. Packaged equivalents like LM334SM/NOPB require redesigning the PCB layout to accommodate surface-mount components instead of direct die attachment.
