LM4040CIM7-2.0/NOPB

Overview

The LM4040CIM7-2.0/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments, formerly National Semiconductor. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +125°C and features a maximum temperature coefficient of 70 ppm/°C. It utilizes a SOT323-5L (SC-70) surface-mount package with five pins. The component supports a maximum shunt current of 15 mA and maintains stability under capacitive loads.

Feature Summary

Ultra-low operating current suitable for power-restricted designs
High precision with stable output over industrial temperature ranges
Capable of driving capacitive loads without oscillation

Applications

Portable battery-powered instrumentation
Data acquisition systems requiring precise voltage references
Microprocessor supervisory circuits

Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence. Ensure the SC-70 package variant matches the required PCB footprint constraints for the target application design.

Selection Notes

Select this component when space-saving is critical due to its small SC-70 package. Choose based on the required 2.048 V reference level and the need for high accuracy in low-power environments. Consider the thermal performance requirements given the wide operating temperature range and low noise characteristics essential for sensitive analog front ends.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. The series offers various accuracy grades and output voltages. The CIM7 suffix denotes the specific temperature grade and packaging configuration, distinguishing it from other variants like the SOT-23-3L package options available in the same family.
