Frequently Asked Questions
What is the output voltage tolerance of the LM4125AIM5-2.0 and why does it matter for ADC accuracy?
The LM4125AIM5-2.0 delivers a nominal 2.048V output within a range of 2.0439V to 2.052V, a tolerance of roughly ±0.1%, which directly limits full-scale error in 12-bit and 14-bit ADC systems using this reference.
Which package does the LM4125AIM5-2.0 use and how does it fit on a compact PCB?
The device uses a 5-pin SOT-23 package, a surface-mount footprint of approximately 3x1.75 mm, making it easy to place near ADC inputs on tight PCB layouts without consuming significant board area.
In what types of precision measurement systems is the LM4125AIM5-2.0 a good voltage reference choice?
It is well-suited for portable handheld instruments, data loggers, and industrial sensors where a stable 2.048V reference supports 12-bit resolution conversion with minimal full-scale error across the operating temperature range.
How does the LM4125AIM5-2.0 compare to a 2.5V reference for 3.3V-supplied ADC designs?
A 2.048V reference fits neatly within a 3.3V supply headroom and provides a convenient binary reference voltage (2^11 mV per LSB at 12 bits), simplifying code-to-voltage conversion compared to a 2.5V reference in low-voltage designs.
