Overview
The LM285BYMX-2.5/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, featuring a fixed output of 2.5 V with an initial accuracy of 1.5%. It operates within a temperature range of -40°C to +85°C and exhibits a temperature coefficient of 150 ppm/°C. The device supports a maximum shunt current of 20 mA and utilizes an SOIC-8 surface-mount package.
Feature Summary
- Provides a stable 2.5 V reference voltage suitable for precision applications
- Operates efficiently at micropower levels with low quiescent current consumption
- Maintains performance stability across industrial temperature ranges
Applications
- Portable instrumentation requiring low power consumption
- Battery-powered measurement systems
- Data acquisition circuits needing precise voltage references
Procurement Notes
Verify the specific suffix 'NOPB' confirms lead-free compliance and RoHS status as per the manufacturer's datasheet. Ensure the SOIC-8 package variant matches your PCB footprint requirements. Confirm the 1.5% initial accuracy grade meets your circuit tolerance specifications before finalizing procurement orders.
Selection Notes
Select this component when a fixed 2.5 V reference is required in a compact surface-mount format. It is appropriate for designs prioritizing low power operation over ultra-high precision. Consider the 150 ppm/°C temperature coefficient against environmental conditions. Compare against adjustable variants if flexible voltage settings are needed instead of a fixed output.
Part Context
This part belongs to the LM285 series of micropower shunt voltage references from Texas Instruments. It shares architectural similarities with other LM285 variants but is distinguished by its fixed 2.5 V output and SOIC-8 packaging. The series is designed for cost-effective, space-constrained applications requiring reliable voltage regulation.
Replacement Considerations
LM285BYMX-2.5/NOPB may be functionally replaced by other LM285 family members with identical voltage and package, such as LM285BYM-2.5/NOPB, provided pinout and thermal characteristics align. Verify datasheet compatibility for any cross-brand substitutes.
