LM4040CIM3X-8.2

Overview

The LM4040CIM3X-8.2 is a micropower shunt voltage reference from Texas Instruments, providing a fixed reverse breakdown voltage of 8.192 V. It operates within an industrial temperature range of -40°C to +85°C and features a maximum initial tolerance of ±0.5% at 25°C. The device requires a minimum operating current of 91 μA and supports a maximum cathode current of 15 mA. Packaged in a surface-mount SOT-23 format, it eliminates the need for external stabilizing capacitors while maintaining stability with capacitive loads.

Feature Summary

Eliminates the need for external stabilizing capacitors
Maintains stability when driving capacitive loads
Utilizes Zener-zap reverse breakdown voltage trimming for precision

Applications

Portable, battery-powered equipment
Data acquisition systems
Instrumentation
Process controls
Precision audio components

Procurement Notes

Verify that the specific ordering suffix matches the required package type and tape-and-reel specifications. Confirm the grade designation corresponds to the necessary accuracy and temperature performance levels. Ensure compatibility with existing board layouts regarding the SOT-23 footprint and pin configuration before finalizing procurement orders.

Selection Notes

Select this component when a stable 8.192 V reference is required in space-constrained designs. The SOT-23 package offers a compact solution for applications where board real estate is limited. Consider the minimum operating current requirements to ensure proper biasing within the circuit design constraints.

Part Context

This device belongs to the LM4040-N family of precision micropower shunt voltage references. The series provides various fixed voltage options ranging from 2.048 V to 10 V. It is designed for high-accuracy applications requiring low power consumption and small physical dimensions without compromising on thermal stability or long-term reliability.
