LM4040AIM3X-4.1/NOPB

Overview

The LM4040AIM3X-4.1/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±0.1%. The device features a temperature coefficient of 100 ppm/°C and operates within a junction temperature range of -40°C to +85°C. It supports a maximum cathode current of 15 mA and draws a typical quiescent current of 67 µA. The component is housed in a SOT-23-3 surface-mount package.

Feature Summary

Provides high-precision fixed voltage reference with tight initial tolerance
Operates with micropower consumption suitable for battery-powered applications
Designed for stable performance across industrial temperature ranges

Applications

Portable instrumentation requiring precise voltage standards
Battery-operated measurement systems
Data acquisition systems needing stable reference sources

Procurement Notes

Verify the complete part number including the /NOPB suffix to ensure lead-free compliance and specific packaging configuration. Confirm that the required accuracy class matches the 'A' grade specification. Check for obsolescence status as availability may vary by region. Ensure the selected package variant aligns with the PCB footprint design requirements.

Selection Notes

Select this component when a fixed 4.096 V reference with ±0.1% initial accuracy is required. The 100 ppm/°C temperature coefficient makes it suitable for general-purpose precision applications. Consider the SOT-23-3 package size for space-constrained designs. Verify that the operating current range meets the system's power budget constraints.

Part Context

This device belongs to the LM4040-N family of precision micropower shunt voltage references from Texas Instruments. The family offers various fixed voltage options and accuracy grades. The LM4040 series is designed to replace larger, less efficient reference solutions in compact electronic designs.

Replacement Considerations

LM4040AIM3X-4.1 is the direct equivalent without the NOPB suffix. LM4040BIM3X-4.1/NOPB offers lower accuracy (±0.2%). LM4050AIM3X-4.1/NOPB provides higher precision (±0.1%) and better temperature stability (50 ppm/°C).
