Overview
The LM4040BIM3X-4.1/NOPB is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 4.096 V with an initial accuracy of 0.2%. The device features a temperature coefficient of 150 ppm/°C and supports a maximum shunt current of 15 mA. It operates within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-3 surface-mount package.
Feature Summary
- Provides stable, fixed precision voltage reference output
- Designed for low-power applications with micropower consumption
- Utilizes compact SOT-23-3 surface-mount packaging
Applications
- Portable battery-powered instrumentation
- Data acquisition systems requiring precise voltage references
- Temperature measurement circuits
Procurement Notes
Verify the specific suffix 'NOPB' indicates lead-free status and RoHS compliance as per Texas Instruments documentation. Confirm the 'X' suffix corresponds to tape-and-reel packaging if reel procurement is required. Ensure the component meets the required initial accuracy and temperature coefficient specifications for the target application environment before ordering.
Selection Notes
Select this component when a fixed 4.096 V reference with 0.2% initial accuracy is required in a small form factor. It is suitable for designs prioritizing low power consumption and moderate temperature stability over a wide industrial range. Consider alternative packages or higher precision grades if tighter thermal drift or lower current limits are necessary.
Part Context
This part belongs to the LM4040-N series of precision micropower shunt voltage references from Texas Instruments. The series offers various fixed voltage options and accuracy grades in the SOT-23 package, designed for space-constrained and battery-operated electronic devices requiring reliable voltage regulation.
Replacement Considerations
LM4040BIM3-4.1/NOPB is a similar variant in the same series with identical electrical specifications but may differ in packaging format.
