Frequently Asked Questions
What is the output voltage and accuracy of the LM4050AEM3-4.1/NOPB?
The LM4050AEM3-4.1/NOPB provides a nominal 4.096V shunt voltage reference with an initial accuracy of ±0.12% (Grade A). The output voltage range spans 4.071V minimum to 4.121V maximum, making it suitable for precision ADC and DAC reference applications where stable voltage is essential.
What package does the LM4050AEM3-4.1/NOPB come in and what are its dimensions?
The LM4050AEM3-4.1/NOPB is housed in a SOT-23-3 (3-pin small outline transistor) package, also identified by JESD-30 code R-PDSO-G3. This compact surface-mount package is ideal for space-constrained PCB designs in portable instruments and handheld electronics where board area is limited.
What are the typical applications for the LM4050AEM3-4.1/NOPB?
This shunt voltage reference is commonly used in ADC and DAC voltage reference circuits, portable measurement instruments, battery-powered sensor systems, industrial signal conditioning, and medical monitoring equipment. Its 4.096V output is especially convenient for 12-bit ADC systems where a 1mV-per-count reference simplifies calibration math.
Is the LM4050AEM3-4.1/NOPB RoHS compliant?
Yes, the LM4050AEM3-4.1/NOPB is fully RoHS compliant. The NOPB suffix indicates a lead-free (Pb-free) version, and it carries a JEDEC JESD-609 e3 moisture sensitivity code, confirming it meets modern green electronics and environmental compliance standards for global use.
What is a suitable replacement or alternative for the LM4050AEM3-4.1/NOPB?
Compatible alternatives include the LM4050B series (higher precision Grade B, ±0.05%) in the same SOT-23-3 package, as well as the LM385-4.1 and REF3040 from Texas Instruments. The LM4040 (parallel/shunt reference) is also a common substitute for applications requiring similar 4.096V precision references in small packages.
