LM4140ACM-1.0/NOPB

Voltage Reference Overview

The LM4140ACM-1.0/NOPB is a micropower low-dropout series voltage reference manufactured by Texas Instruments, housed in an SOIC-8 package. It provides a nominal output voltage of 1.024 V with an initial accuracy of 0.1%. The device features a temperature coefficient of 3 ppm/°C and operates within a junction temperature range of 0°C to +70°C. It draws a typical quiescent current of 265 µA and supports a maximum shunt current of 8 mA. The input voltage must not exceed 5.6 V.

Voltage Reference Feature Summary

Provides high precision voltage referencing with low noise characteristics suitable for sensitive analog circuits.
Features a low dropout design allowing operation with minimal input-to-output voltage differential.
Includes an enable pin for power management control to reduce consumption during inactive periods.

Voltage Reference Applications

Precision data acquisition systems requiring stable reference voltages
Battery-powered instrumentation utilizing micropower components
Calibration equipment needing high initial accuracy

Voltage Reference Procurement Notes

Verify the specific suffix configuration against the manufacturer's latest datasheet to ensure compatibility with your design requirements. Confirm that the component meets all relevant environmental compliance standards required for your target market before finalizing procurement decisions.

Voltage Reference Selection Notes

Select this component when a sub-1.25 V precision reference with low quiescent current is required. Ensure the application voltage does not exceed the 5.6 V maximum input limit. Consider the SOIC-8 package constraints for thermal management and PCB layout space availability.

Voltage Reference Part Context

This part belongs to the LM4140 family of series voltage references from Texas Instruments. It shares architectural similarities with other members like the LM4140BCM variants but differs in output voltage and temperature coefficient specifications. The NOPB suffix indicates lead-free construction compliant with RoHS directives.
