LM4041DIM7X-1.2/NOPB

Voltage Reference Overview

The LM4041DIM7X-1.2/NOPB is a precision micropower shunt voltage reference from Texas Instruments, featuring a fixed output of 1.225 V. It operates within an industrial temperature range of -40°C to +85°C and utilizes a SC-70 (IM7) surface-mount package with five pins. The device offers an initial accuracy of ±0.5% at 25°C and maintains a low temperature coefficient of 150 ppm/°C. Designed for stability without external capacitors across all capacitive loads, it supports a wide operating current range from a minimum of 45 µA to a maximum of 12 mA.

Voltage Reference Procurement Notes

Verify the specific suffix 'DIM7X' corresponds to the SC-70 package and tape-and-reel delivery format as indicated by distributor listings. Confirm that the 'NOPB' designation ensures compliance with lead-free manufacturing standards. Cross-reference the part number against the official Texas Instruments datasheet to ensure alignment with the specified 1.225V fixed output and industrial temperature grade before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when space-constrained designs require a sub-miniature SC-70 footprint instead of larger SOT-23 packages. It is suitable for applications demanding micropower operation with a minimum current of 45 µA. Choose this variant over automotive grades if the operating environment remains within the -40°C to +85°C industrial range rather than requiring extended temperature capabilities up to 125°C.
