LM4040DIM7X-2.5/NOPB

Overview

The LM4040DIM7X-2.5/NOPB is a micropower shunt voltage reference with a fixed output of 2.5 V. It features an initial accuracy of 1% and a temperature coefficient of 150 ppm/°C. The device operates within a temperature range of -40°C to +85°C. It is housed in a SC-70-5 (SOT-363) surface-mount package. Key electrical parameters include a maximum cathode current of 12 mA, a minimum operating current of 4.5 µA, and a noise level of 35 µVrms from 10 Hz to 10 kHz.

Feature Summary

Micropower operation with a minimum operating current of 4.5 µA for battery-powered applications
Compact SC-70-5 surface-mount package design
Low noise performance suitable for precision analog circuits

Applications

Portable instrumentation requiring low power consumption
Battery-operated measurement devices
Precision data acquisition systems

Procurement Notes

Verify the specific suffix DIM7X corresponds to the SC-70-5 package configuration. Confirm the 2.5 V output voltage and 1% tolerance match system requirements. Ensure compatibility with the -40°C to +85°C industrial temperature range. Check for RoHS compliance status indicated by the NOPB suffix.

Selection Notes

Select this component when a small footprint and ultra-low quiescent current are critical. The 1% accuracy is sufficient for general-purpose references where higher precision is not required. Compare against the SOT-23-3 packaged variants if board space allows for larger components with potentially different thermal characteristics.

Part Context

This part belongs to the LM4040-N series of precision shunt voltage references from Texas Instruments. The series offers various output voltages and packages. The LM4040DIM7X variant specifically utilizes the SC-70-5 package, distinguishing it from the more common SOT-23-3 versions like the LM4040DIM3X.
