Overview
The LM4040C20ILP is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40°C to +85°C and features a maximum shunt current of 15 mA. It utilizes a TO-92-3 through-hole package, ensuring compatibility with standard prototyping and industrial applications requiring stable voltage references.
Feature Summary
- Provides a fixed 2.048 V output for precise circuit referencing
- Operates as a micropower shunt reference with low quiescent current
- Maintains high accuracy with ±0.5% initial tolerance
- Designed for reliable performance across extended industrial temperature ranges
Applications
- Portable instrumentation requiring stable voltage references
- Battery-powered measurement systems
- Data acquisition systems
- Industrial process control loops
Procurement Notes
Verify the specific suffix 'ILP' corresponds to the TO-92-3 through-hole package configuration. Confirm that the 'C' grade indicates the required ±0.5% accuracy level for your application. Ensure the operating temperature range of -40°C to +85°C meets your environmental specifications before procurement.
Selection Notes
Select this component when a fixed 2.048 V reference is needed in a through-hole format. Compare against SOT-23 variants if board space is limited. Verify that the 15 mA maximum shunt current is sufficient for your load requirements. Consider the ±0.5% tolerance if higher precision grades are not necessary.
Part Context
This part belongs to the LM4040 family of micropower shunt voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades. The ILP designation specifically identifies the TO-92-3 package style, distinguishing it from surface-mount options like DBZ or IM3 packages within the same electrical family.
Replacement Considerations
LM4040C20ILPR is the reel version of the same component. LM4040BIM3-2.0/NOPB offers similar voltage in a surface-mount SOT-23 package. Verify pinout compatibility when substituting with other manufacturers' equivalents.
