Overview
The LM285BXM-2.5/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It provides a fixed output voltage of 2.5 V with an initial accuracy of 1.5%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 150 ppm/°C. It supports a maximum shunt current of 20 mA and is RoHS compliant.
Feature Summary
- Provides a stable 2.5 V reference voltage suitable for precision applications
- Operates efficiently at micropower levels with low quiescent current
- Maintains performance across industrial temperature ranges
Applications
- Portable instrumentation circuits requiring low power consumption
- Data acquisition systems utilizing analog-to-digital converters
- Battery-powered measurement devices
Procurement Notes
Verify the specific suffix NOPB indicates lead-free compliance when sourcing. Confirm the SOIC-8 package variant matches the intended PCB footprint. Ensure the 1.5% initial accuracy meets the system requirements. Check for any recent manufacturing changes or obsolescence notices from Texas Instruments before finalizing procurement plans.
Selection Notes
Select this component when a fixed 2.5 V reference is required in a compact surface-mount form factor. 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. It shares architectural similarities with other LM285 variants but differs in its fixed 2.5 V output and SOIC-8 packaging. The series is designed for cost-effective, low-power reference solutions in consumer and industrial electronics.
Replacement Considerations
LM285BYMX-2.5/NOPB offers similar specifications with potentially different initial accuracy grades. LM285Z-2.5/NOPB provides the same voltage in a through-hole TO-92 package. Verify pinout compatibility and thermal characteristics when substituting.
