LM4040CIM7-2.5/NOPB

Overview

The LM4040CIM7-2.5/NOPB is a micropower shunt voltage reference with a nominal output of 2.5V and ±0.5% initial accuracy. It operates within a temperature range of -40°C to +85°C, featuring a maximum cathode current of 15mA and a minimum operating current of 65µA. The device utilizes an SC-70-5 surface-mount package, measuring 1.6mm x 1.3mm x 0.55mm. It exhibits a temperature coefficient of 150ppm/°C and low noise characteristics.

Feature Summary

Micropower shunt architecture for efficient biasing
Compact SC-70-5 footprint for space-constrained designs
High initial accuracy for precision applications

Applications

Portable instrumentation circuits
Battery-powered measurement systems
Data acquisition signal conditioning

Procurement Notes

Verify the specific suffix 'CIM7' against official Texas Instruments documentation to confirm the SC-70-5 package variant. Ensure the order matches the exact part number including the '/NOPB' designation for lead-free compliance. Cross-reference the datasheet for thermal performance requirements in the small outline package.

Selection Notes

Select this component when a compact surface-mount voltage reference is required for low-power applications. The SC-70-5 package offers significant size reduction compared to traditional TO-92 or SOT-23 options. Consider the 150ppm/°C temperature coefficient for environmental stability requirements.

Part Context

This part belongs to the LM4040-N series of precision micropower shunt references. It provides stable voltage regulation in a miniature form factor suitable for modern PCB layouts. The series is designed for applications requiring high accuracy and low power consumption in portable devices.
