LM4040D20ILP

Overview

The LM4040D20ILP is a two-terminal shunt voltage reference IC manufactured by Texas Instruments. It provides a fixed output voltage of 2.048V with an initial accuracy tolerance of ±1%. The device operates within a temperature range of -40°C to 85°C and features a temperature coefficient of 150ppm/°C. It supports a maximum cathode current of 15mA and requires a minimum operating current of 80µA. The component utilizes a TO-92-3 through-hole package.

Feature Summary

Provides a stable, fixed reference voltage for precision circuit applications
Operates as a two-terminal shunt device requiring minimal external components
Maintains specified performance across standard industrial temperature ranges

Applications

Precision analog-to-digital converter (ADC) reference sources
Portable instrumentation voltage regulation
Battery-powered measurement equipment references
Microprocessor power supply supervision circuits

Procurement Notes

Verify the specific suffix 'ILP' corresponds to the TO-92-3 through-hole package configuration rather than surface-mount variants. Confirm that the 'D' accuracy grade matches the required ±1% tolerance for the design. Ensure the manufacturer source is authorized to prevent counterfeit components in legacy through-hole packages.

Selection Notes

Select this part when a low-cost, through-hole shunt reference is required for fixed voltage applications. The 2.048V output is suitable for driving ADCs or DACs directly. Consider the 15mA load capability and 80µA minimum current requirement during biasing design. Evaluate thermal dissipation if operating near maximum current limits in enclosed environments.

Part Context

This component belongs to the LM4040 series of micropower shunt voltage references. The series offers various fixed voltage options and accuracy grades. The LM4040D20ILP specifically denotes the 2.048V output version with ±1% tolerance in a traditional TO-92-3 leaded package, distinguishing it from SOT-23 surface-mount equivalents.
