LM4040C41QFTA

Overview

The LM4040C41QFTA is an automotive compliant precision micropower shunt voltage reference manufactured by Diodes Incorporated. It provides a fixed output voltage of 4.096 V with an initial tolerance of ±0.5% at +25°C. The device operates within a wide current range of 60 µA to 15 mA and maintains stability over an extended temperature range from -40°C to +125°C. It features a maximum temperature coefficient of 100 ppm/°C and low output noise. Packaged in a compact SOT-23 surface mount format, it is AEC-Q100 qualified and suitable for space-constrained automotive designs.

Feature Summary

Automotive grade qualification supporting specific change control requirements
Capacitive load tolerant design eliminating the need for output capacitors
Micropower operation optimized for power-restricted applications

Applications

Automotive reference voltages
Automotive data acquisition systems

Procurement Notes

Verify that the component matches the exact part number LM4040C41QFTA to ensure correct voltage and tolerance specifications. Confirm the package type is SOT-23 and check for AEC-Q100 compliance if automotive standards are required. Ensure the ordering suffix indicates tape and reel packaging as specified in the manufacturer documentation.

Selection Notes

Select this component when a stable 4.096 V reference is needed in automotive environments. The C-grade offers a balance of precision and cost. Verify that the operating current remains within the 60 µA to 15 mA range to maintain specified performance. Consider the SOT-23 package size for PCB layout constraints.
