Frequently Asked Questions
What is the output voltage and accuracy of the LM4040AIM3-10.0?
The LM4040AIM3-10.0 provides a 10V shunt reference voltage with an output range of 9.925V to 10.075V, corresponding to ±0.75% initial accuracy. This tight tolerance makes it suitable for precision measurement and calibration applications requiring a stable 10V reference.
How does the LM4040AIM3-10.0 two-terminal configuration work?
As a two-terminal shunt voltage reference, the LM4040AIM3-10.0 operates like a precision Zener diode — it is placed in parallel with the load and requires only a series current-limiting resistor. This eliminates the need for external bypass capacitors or additional components, simplifying PCB layout and reducing BOM cost.
What package does the LM4040AIM3-10.0 use and what are its dimensions?
The LM4040AIM3-10.0 uses a SOT-23 3-pin surface-mount package, which is one of the smallest standard IC packages. This compact form factor is ideal for space-constrained designs such as portable instruments, handheld meters, and densely packed industrial PCBs.
What are typical applications for the LM4040AIM3-10.0?
Typical applications include ADC and DAC voltage references, precision current sources, industrial sensor signal conditioning, portable test and measurement equipment, battery-powered instrumentation, and any circuit requiring a stable 10V reference in a minimal footprint.
