LM4040BIM3-8.2/NOPB

Overview

The LM4040BIM3-8.2/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 8.2V. It features an initial accuracy of ±0.2% and operates within a temperature range of -40°C to +85°C. The device utilizes a SOT-23 surface-mount package with three pins. Key electrical characteristics include a maximum shunt current of 15mA and a minimum operating current of 60µA. It is designed for applications requiring precision voltage referencing in space-constrained environments.

Feature Summary

Provides a stable fixed reference voltage suitable for precision analog circuits
Operates with low quiescent current to minimize power consumption
Delivers high initial accuracy for precise measurement systems
Utilizes a compact surface-mount package for efficient board layout

Applications

Portable instrumentation requiring low power consumption
Battery-powered measurement devices
Data acquisition systems needing stable reference voltages
Temperature sensing circuits utilizing bridge configurations

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free composition and RoHS compliance as per manufacturer standards. Confirm the 'B' grade designation corresponds to the required ±0.2% initial accuracy tolerance for your application. Ensure the SOT-23-3 footprint matches your PCB design constraints. Check for any recent product change notices regarding packaging or material updates.

Selection Notes

Select this component when a fixed 8.2V reference is required with high precision. Consider the low operating current if battery life is critical. Verify that the shunt current capability meets the load requirements. Compare against other grades in the LM4040 series if tighter tolerances or different voltage outputs are needed. Ensure thermal management aligns with the specified operating temperature range.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The family offers various fixed voltage options in a small SOT-23 package. These devices are designed for applications where size and power consumption are primary concerns. The LM4040 series is widely used in industrial and consumer electronics for providing stable reference points.
