LM4040D41IDCKR

Overview

The LM4040D41IDCKR is a precision micropower shunt voltage reference from Texas Instruments. It provides a fixed output voltage of 4.096V with an initial accuracy of ±1% and a temperature coefficient of 150ppm/°C. The device operates within a cathode current range of 45μA to 15mA and functions over an ambient temperature range of -40°C to 85°C. It is housed in a space-saving SC-70 (SC-70-5) surface-mount package.

Feature Summary

Stable with all capacitive loads without requiring an external output capacitor
Low dynamic impedance and low noise for stable performance across operating currents
Fuse and Zener-zap reverse breakdown voltage trim during wafer sort ensures tight tolerances

Applications

Data-Acquisition Systems
Energy Infrastructure
Analog Input Module
Field Transmitters
Precision Audio

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest Package Option Addendum to confirm the exact pin configuration and package dimensions. Ensure the selected grade meets the required initial accuracy and temperature coefficient specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when a fixed 4.096V reference with ±1% tolerance is required in a compact SC-70 footprint. It is suitable for portable applications due to its micropower characteristics and stability with capacitive loads. Verify that the industrial temperature range (-40°C to 85°C) aligns with the system's thermal requirements.

Part Context

This part belongs to the LM4040 series of shunt voltage references, which offers various fixed output voltages and grades. The 'D' indicates the D-grade with 1% accuracy, '41' specifies the 4.096V output, 'I' denotes the industrial temperature range, and 'DCK' identifies the SC-70-5 package type.
