Frequently Asked Questions
What is the output voltage accuracy and temperature coefficient of the LM4040QCIM3X2.5/NOPB?
The LM4040QCIM3X2.5/NOPB provides a 2.5 V nominal reference output with a tight accuracy of 2.488 V to 2.512 V, corresponding to ±0.5% initial accuracy. Its temperature coefficient is 100 ppm/°C, ensuring stable voltage over the full automotive operating range of -40°C to +125°C, which is critical for precise ADC conversions in automotive sensor interfaces.
How does the LM4040QCIM3X2.5/NOPB compare to series voltage references for automotive designs?
The LM4040QCIM3X2.5/NOPB is a two-terminal shunt reference, which means it operates like a precision Zener diode and requires a series resistor to set operating current. Unlike series references, it has no enable pin and draws quiescent current continuously, but its simplicity and compact SOT-23 3-pin package make it ideal for space-constrained automotive ECU and sensor PCBs where the 2.5 V reference rail is always active.
Which automotive applications benefit most from the LM4040QCIM3X2.5/NOPB reference?
Automotive ADC reference circuits, throttle position sensors, battery management system analog front ends, and ADAS radar signal processing boards benefit most from this device. Its AEC-Q100 qualification and 100 ppm/°C temperature stability ensure reliable 2.5 V reference performance from cold start at -40°C through full engine-bay operation at +125°C, meeting the stringent requirements of automotive safety-critical electronic systems.
What is the package and pin count of the LM4040QCIM3X2.5/NOPB, and how does it simplify PCB layout?
The LM4040QCIM3X2.5/NOPB is housed in a SOT-23 3-pin package, one of the smallest industry-standard through-mount-compatible surface-mount packages. With only 3 pins and a footprint under 3 mm x 1.5 mm, it minimizes PCB real estate usage in automotive modules, simplifying layout for tight-pitch designs and enabling placement close to the ADC reference input pin to reduce trace-length noise pickup.
