LM4040CIM3X-3.0/NOPB

Overview

The LM4040CIM3X-3.0/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, operating within the LM4040 series. It provides a fixed output voltage of 3.0 V with an initial accuracy of ±0.5%. The device features a temperature coefficient of 100 ppm/°C and operates in a surface-mount SOT-23-3 package. Electrical specifications include a maximum shunt current of 15 mA and a minimum operating current of 60 µA. It supports a maximum input voltage of 5 V and functions reliably across a temperature range from -40°C to +85°C.

Feature Summary

Provides stable precision voltage referencing through a shunt topology design
Operates with micropower consumption suitable for battery-powered applications
Delivers consistent performance across industrial temperature ranges

Applications

Portable instrumentation requiring low power consumption
Battery-operated measurement systems
Data acquisition circuits needing precise analog references

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure compatibility with required accuracy and packaging standards. Confirm RoHS compliance status as indicated in manufacturer documentation. Check for lead-free designation markers on component markings. Validate that the ordering part number matches the exact electrical tolerances required for the target application circuit design.

Selection Notes

Select this component when a fixed 3.0 V reference is required in a compact SOT-23-3 footprint. Consider the ±0.5% initial accuracy and 100 ppm/°C temperature coefficient for precision requirements. Ensure the circuit design accommodates the 15 mA maximum shunt current capability. Evaluate the 60 µA minimum operating current constraint for low-power standby modes.

Part Context

This component belongs to the LM4040 family of micropower shunt voltage references from Texas Instruments. The series offers various fixed voltage options and accuracy grades. The CIM3X variant specifically denotes the commercial grade temperature range and tape-and-reel packaging format. It serves as a standard reference solution for general-purpose analog signal conditioning tasks.
