LM4040BIM-10.0

Overview

The LM4040BIM-10.0 is a precision micropower shunt voltage reference manufactured by National Semiconductor, now part of Texas Instruments. It provides a fixed output voltage of 10.0 V with an initial accuracy of ±0.2%. The device features a maximum temperature coefficient of 100 ppm/°C and operates within a wide current range from 60 µA to 15 mA. It is housed in a compact SOT-23 surface-mount package.

Feature Summary

• Provides a stable 10.0 V reference voltage with high initial accuracy
• Operates over a wide temperature range suitable for industrial applications
• Designed for space-constrained designs using a small SOT-23 package

Applications

• Portable battery-powered equipment
• Industrial process control systems
• Data acquisition systems requiring precise voltage references

Procurement Notes

Verify the manufacturer status as National Semiconductor has been acquired by Texas Instruments. Confirm that the specific suffix indicates the 10.0 V output variant and check for any lead-free or RoHS compliance markings on the component marking code. Ensure the package type matches the required PCB footprint for SOT-23 mounting.

Selection Notes

Select this component when a 10.0 V reference is required with ±0.2% initial accuracy. It is suitable for applications needing low power consumption and stability across varying temperatures. Consider the SOT-23 package size if board space is limited compared to larger packages like SOP or DIP.

Part Context

This component belongs to the LM4040 family of precision micropower shunt voltage references. The 'B' suffix typically denotes the ±0.2% accuracy grade. The 'IM' indicates the SOT-23 package style. The '-10.0' specifies the fixed 10.0 V output voltage option available within this product line.

Replacement Considerations

LM4040BIM3-10.0/NOPB is a confirmed equivalent part number from Texas Instruments offering identical electrical specifications and pinout compatibility.
