LM4140ACMX-1.0/NOPB

Voltage Reference Overview

The LM4140ACMX-1.0/NOPB is a micropower low-dropout series voltage reference manufactured by Texas Instruments, housed in an SOT-23 package. It provides a fixed output voltage of 1.024 V with an initial accuracy of 0.1%. The device features a temperature coefficient of 6 ppm/°C and operates within a supply voltage range up to 5.6 V. Maximum shunt current is 8 mA, with quiescent current typically around 230 µA. It functions across a temperature range of -40°C to +85°C.

Voltage Reference Feature Summary

High precision series voltage reference architecture
Micropower operation for battery efficiency
Low dropout performance for wide input ranges
Integrated enable pin for power management

Voltage Reference Applications

Portable instrumentation systems
Battery-powered measurement devices
Data acquisition channels
Precision analog front ends

Voltage Reference Procurement Notes

Verify the specific suffix 'CMX' indicates the SOT-23 surface-mount package variant distinct from the SOIC-8 'CM' version. Confirm the '-NOPB' designation ensures lead-free compliance and RoHS standards. Cross-reference the manufacturer's latest datasheet revision to ensure compatibility with current design specifications and environmental regulations.

Voltage Reference Selection Notes

Select this component when a compact SOT-23 footprint is required alongside high precision. The 1.024 V output suits applications needing sub-2V references. Ensure the system can accommodate the 6 ppm/°C drift. Compare against LM4140BCM variants if tighter 3 ppm/°C stability is necessary for the specific operating environment.

Voltage Reference Part Context

This part belongs to the LM4140 family of micropower series voltage references. It complements other members like the LM4140ACM-2.0/NOPB which offers different voltage options. The family is designed for applications requiring stable, low-noise references in space-constrained designs without sacrificing accuracy or power efficiency.
