LM385BM-1.2

Overview

The LM385BM-1.2 is a micropower shunt voltage reference diode manufactured by Texas Instruments, belonging to the LM385B series. It provides a nominal output voltage of 1.235 V with an initial accuracy of ±1%. The device features a temperature coefficient of 20 ppm/°C and supports a maximum shunt current of 20 mA. It operates within a commercial temperature range of 0°C to +70°C and is available in an 8-pin SOIC surface-mount package.

Feature Summary

Provides stable 1.235 V reference via shunt topology
Ensures high precision with ±1% initial accuracy
Maintains stability across temperature variations with low drift

Applications

Precision analog-to-digital converter reference inputs
Battery-powered instrumentation circuits
Portable measurement equipment requiring low power consumption

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific packaging variants (e.g., tape and reel vs. tube) prior to ordering. Ensure the selected suffix matches the required package type and lead-free specifications for your assembly process.

Selection Notes

Select this component when a fixed 1.235 V reference with tight tolerance is required in a surface-mount format. Compare against the adjustable LM385M variant if programmable voltage is needed. Consider the LM385BLP for through-hole applications with similar electrical characteristics but different physical mounting requirements.

Part Context

This part belongs to the broader LM385 family of micropower voltage references, which includes industrial and military grade variants like the LM185 and LM285. The 'B' designation indicates tighter performance specifications compared to standard grades. It serves as a drop-in replacement for legacy National Semiconductor versions of the same specification.
