LM385BXMX-2.5/NOPB

Overview

The LM385BXMX-2.5/NOPB is a shunt voltage reference IC manufactured by Texas Instruments, housed in an 8-SOIC surface-mount package. It provides a fixed output voltage of 2.5V with an initial accuracy tolerance of ±1.5%. The device operates within a temperature range of -40°C to +85°C and features a temperature coefficient of 150ppm/°C. Key electrical specifications include a maximum shunt current of 20mA and a minimum cathode current of 20µA.

Feature Summary

Provides a stable 2.5V reference voltage suitable for precision applications
Operates reliably across an extended industrial temperature range from -40°C to +85°C
Designed for low-power consumption with microampere-level bias current requirements

Applications

Precision analog-to-digital converter (ADC) reference sources
Data acquisition systems requiring stable voltage references
Battery-powered instrumentation circuits

Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance status as per the manufacturer's datasheet. Confirm the package type matches the design footprint. Check for obsolescence notices or lifecycle changes directly from Texas Instruments documentation before finalizing procurement plans.

Selection Notes

Select this component when a fixed 2.5V reference with ±1.5% accuracy is required in an SOIC-8 package. Ensure the application environment stays within the -40°C to +85°C operating range. Compare against adjustable variants if circuit flexibility is needed, or higher precision parts if tighter tolerances are necessary.

Part Context

This part belongs to the LM385 family of micropower shunt voltage references. It serves as a drop-in replacement for older non-RoHS versions like the LM385MX-2.5, offering environmental compliance while maintaining similar electrical characteristics and pinout compatibility for legacy designs.
