Frequently Asked Questions
What is the output voltage of the LM4125IM5-2.0?
The LM4125IM5-2.0 provides a nominal output voltage of 2.048V, with a specified minimum of 2.03776V and a maximum of 2.05824V. This tight tolerance makes it ideal as a precision reference for 12-bit and higher ADC/DAC systems where reference accuracy directly impacts measurement resolution.
What type of voltage reference is the LM4125IM5-2.0?
The LM4125IM5-2.0 is a three-terminal LDO (low-dropout) voltage reference. The three-terminal configuration means it has input, output, and ground pins, operating similarly to a low-dropout regulator but optimized for reference accuracy and stability rather than high output current capability.
What package does the LM4125IM5-2.0 come in?
The LM4125IM5-2.0 is housed in a SOT-23 5-pin package, identified by JESD-30 code R-PDSO-G5. This very compact surface-mount package makes it ideal for space-constrained designs in portable instrumentation, handheld devices, and compact PCBs where minimizing footprint is critical.
Is the LM4125IM5-2.0 suitable for use as an ADC reference?
Yes, the LM4125IM5-2.0 is well-suited as a voltage reference for ADC and DAC applications. Its 2.048V nominal output is a commonly used reference value for 12-bit converters, and its tight output tolerance (less than ±1% from nominal) ensures that the converter's full-scale accuracy is not significantly degraded by the reference.
What are the key application areas for the LM4125IM5-2.0?
The LM4125IM5-2.0 is used in precision voltage reference applications including data acquisition systems, test and measurement instrumentation, sensor signal conditioning, and portable battery-powered devices. Its stable 2.048V output and compact SOT-23 package make it a practical choice for any system requiring an accurate low-voltage reference in a minimal board footprint.
