LM4040BIM3-2.0

Overview

The LM4040BIM3-2.0 is a micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed output of 2.048 V. It offers an initial accuracy of ±0.2% and operates within a temperature range of -40°C to +85°C. The device utilizes a SOT-23-3 surface-mount package with a maximum shunt current of 15 mA and a typical operating current of 10 µA at 25°C.

Feature Summary

• Provides stable reference voltage across industrial temperature ranges
• Ultra-low operating current suitable for power-constrained designs
• High precision with ±0.2% initial accuracy tolerance

Applications

• Portable battery-powered instrumentation
• Data acquisition systems
• Handheld meters

Procurement Notes

Verify the specific suffix 'M3' indicates the SOT-23-3 package variant. Confirm the '-2.0' designation corresponds to the 2.048 V output version. Ensure compatibility with the required thermal environment and load conditions before procurement.

Selection Notes

Select this component when space-saving SOT-23 packaging is required alongside high precision. It is appropriate for applications demanding low quiescent current and stable performance over varying temperatures without requiring series regulator topology.

Part Context

This part belongs to the LM4040 family of micropower shunt references. It shares architectural similarities with other variants in the series but is distinguished by its specific 2.048 V output and B-grade accuracy classification.

Replacement Considerations

LM4040AIM3-2.0/NOPB provides equivalent functionality with higher precision.
