Overview
The LM285Z-2.5/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, housed in a TO-92-3 through-hole 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. Maximum shunt current is rated at 20 mA, supporting low-power applications requiring stable precision references.
Feature Summary
- Provides a precise 2.5 V reference voltage suitable for high-accuracy analog circuits
- Operates efficiently with micropower consumption across a wide current range
- Maintains stability over industrial temperature variations with controlled drift characteristics
Applications
- Analog-to-digital converter (ADC) reference sources
- Digital-to-analog converter (DAC) voltage standards
- Portable instrumentation requiring low power supply
- Sensor interface circuit biasing
Procurement Notes
Verify the component matches the specific Texas Instruments part number LM285Z-2.5/NOPB to ensure correct voltage tolerance and package type. Confirm RoHS compliance status as indicated by the NOPB suffix. Check datasheet specifications for operating temperature range and maximum shunt current limits before integration into final designs.
Selection Notes
Select this component when a fixed 2.5 V reference is required in a through-hole TO-92-3 package. It is appropriate for designs needing 1.5% initial accuracy and operation up to 85°C. Consider the 150 ppm/°C temperature coefficient for thermal stability requirements. Ensure the application current remains within the 10 µA to 20 mA operational window for optimal performance.
Part Context
This device belongs to the LM285 series of micropower shunt voltage references from Texas Instruments. It utilizes bandgap reference technology to deliver stable output voltages. The LM285Z-2.5/NOPB variant specifically offers a fixed 2.5 V output, distinguishing it from adjustable versions like the LM285BXZ or other fixed voltage variants within the same family.
Replacement Considerations
LM285Z-2.5/NOPB serves as a direct replacement for LM285Z-2.5. Other compatible variants include LM285Z-2.5#PBF and LM285Z-2.5#TRPBF, provided package and electrical specifications align with design requirements.
