This precision voltage reference module takes LM4040 as the core component, providing two classic fixed reference voltages of 2.048V and 4.096V, which are perfectly matched with the ADC sampling calibration of most microcontrollers.
Different from simple resistor voltage division circuits, this module features outstanding temperature stability and low noise performance. It can offer a reliable fixed voltage benchmark, greatly improving the accuracy of voltage collection, signal detection and instrument measurement.
The PCB adopts compact layout with clear positive and negative pins, easy to connect with breadboards, development boards and experimental circuits. Built-in anti-reverse protection components avoid chip damage caused by wrong wiring.
Suitable for electronic makers, engineering debugging, student electronic projects and industrial signal acquisition equipment. It is an indispensable auxiliary module to improve the sampling precision of microcontroller systems.
