LM4040AIM3X-2.0/NOPB

Overview

The LM4040AIM3X-2.0/NOPB is a micropower shunt voltage reference from Texas Instruments, offering a fixed output of 2.048V with ±0.1% initial accuracy. It operates within a temperature range of -40°C to 85°C and features a temperature coefficient of 100 ppm/°C. The device supports a maximum cathode current of 15 mA and includes low noise characteristics (35 µVrms from 10Hz to 10kHz). Packaged in a compact SOT-23-3 surface-mount format, it is designed for precision applications requiring stable voltage regulation.

Feature Summary

Provides high-precision voltage regulation with ±0.1% initial accuracy
Features low noise performance suitable for sensitive analog circuits
Operates efficiently as a micropower shunt reference

Applications

Precision data acquisition systems
Portable instrumentation
Battery-powered measurement devices

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free compliance and RoHS adherence. Confirm the 'X' designation corresponds to tape-and-reel packaging if bulk supply is required. Ensure the operating environment stays within the specified -40°C to 85°C thermal limits to maintain the stated 100 ppm/°C stability. Cross-reference the exact part number against the manufacturer's latest datasheet to confirm current production status.

Selection Notes

Select this component when a fixed 2.048V reference with tight tolerance is required in a small footprint. It is suitable for designs needing low quiescent current and minimal noise interference. Compare against other LM4040 variants if different voltage outputs or accuracy grades are needed. Ensure the circuit design accommodates the shunt topology requirements for proper biasing.

Part Context

This part belongs to the LM4040 series of micropower shunt voltage references. It shares the same package and basic functionality as other members like the LM4040AIM3-2.5 but provides a specific 2.048V output. The series is known for its compact size and reliability in portable electronics.
