Frequently Asked Questions
What is the output voltage and accuracy of the LM4120AIM5-2.5/NOPB?
The LM4120AIM5-2.5/NOPB provides a fixed 2.5V output with 0.2% initial accuracy, meaning the output voltage is guaranteed between 2.495V and 2.505V. This tight tolerance makes it suitable for driving 12-bit and 14-bit ADC or DAC references in precision measurement applications.
What is the temperature coefficient of the LM4120AIM5-2.5/NOPB and why does it matter?
The device features a maximum temperature drift of 50ppm/°C, which means the output voltage shifts by no more than 0.125mV per degree Celsius change. This low drift is critical in industrial and medical instrumentation where ambient temperature varies widely and reference stability directly affects measurement accuracy.
What package does the LM4120AIM5-2.5/NOPB use and what is its input voltage range?
The LM4120AIM5-2.5/NOPB is housed in a compact SOT-23 5-pin package, ideal for space-constrained PCB designs. It operates from an input voltage of 2V to 12V, providing flexibility across a wide range of supply rails commonly found in portable, industrial, and battery-powered systems.
How does the shutdown enable feature benefit system design?
The shutdown enable pin allows the host microcontroller or power management IC to turn off the voltage reference when not in use, reducing standby current consumption. This feature is especially valuable in portable and IoT devices where minimizing quiescent current extends battery life without sacrificing precision when the reference is active.
