LM4040CIZ-10.0

Overview

The LM4040CIZ-10.0 is a micropower shunt voltage reference manufactured by National Semiconductor, now part of Texas Instruments. It provides a fixed 10V output with an initial accuracy of ±0.5%. The device operates within an industrial temperature range of -40°C to +85°C and features a maximum temperature coefficient of 100 ppm/°C. It is housed in a TO-92-3 plastic package.

Feature Summary

• Provides stable fixed output voltage suitable for precision applications
• Operates reliably across the full industrial temperature range
• Designed for low power consumption in space-constrained environments

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-powered systems prioritizing low current draw
• Data acquisition systems needing accurate analog references

Procurement Notes

Verify that the component is sourced from authorized distributors to ensure authenticity. Confirm the specific suffix matches the required tolerance and package type. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure the supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a 10V reference with ±0.5% accuracy is required. Consider the TO-92 package for through-hole mounting requirements. Evaluate the 100 ppm/°C temperature coefficient against your system's thermal stability needs. Compare operating current specifications with other shunt references if power efficiency is critical.

Part Context

This part belongs to the LM4040 family of micropower shunt voltage references. The series offers various fixed output voltages including 2.048V, 2.5V, 3.0V, 4.096V, and 5.0V. Different suffixes indicate variations in accuracy grades such as A (0.1%), B (0.2%), C (0.5%), and D (1%). The LM4040CIZ-10.0 specifically denotes the 10V output version with C-grade accuracy.
