Overview
The LM185BH/NOPB is an adjustable micropower shunt voltage reference manufactured by Texas Instruments. It operates within a temperature range of -55°C to +125°C and utilizes a TO-3 through-hole package. The device provides an output voltage range from 1.24 V to 5.3 V with an initial accuracy of 1% and a temperature coefficient of 150 ppm/°C. Maximum shunt current is rated at 20 mA, and the minimum operating current is 10 µA.
Feature Summary
- Adjustable output voltage capability via external resistor network
- High precision performance with 1% initial accuracy
- Wide industrial temperature operation extending to -55°C
Applications
- Precision analog-to-digital converter references
- Battery-powered instrumentation circuits
- Temperature-compensated oscillator designs
Procurement Notes
Verify the specific suffix configuration against official datasheets to confirm pinout compatibility and electrical specifications. Ensure the TO-3 package style matches the target PCB or chassis mounting requirements. Confirm RoHS compliance status for environmental regulations. Cross-reference manufacturer part numbers to avoid counterfeit components during sourcing.
Selection Notes
Select this component when high precision and wide temperature stability are required in a through-hole form factor. The 1% initial accuracy suits applications demanding tight tolerance without trimming. Consider the TO-3 package size constraints relative to available board space. Evaluate thermal management needs given the maximum shunt current rating of 20 mA.
Part Context
This device belongs to the LM185-ADJ series of micropower voltage references. It serves as a stable baseline for analog signal processing systems. The family is characterized by low power consumption and robust performance across extreme environmental conditions. It complements other Texas Instruments precision analog components.
Replacement Considerations
Consult official substitution guides for equivalent adjustable shunt references. Verify that alternative parts match the TO-3 package dimensions and pin assignments. Ensure replacement devices meet the same 1% accuracy and 150 ppm/°C temperature coefficient specifications.
