Precision reference for microcontroller circuits
This Vszerda module provides stable 2.048 V and 4.096 V outputs based on the LM4040 voltage reference. It serves engineers and hobbyists who need accurate, low-drift reference voltages for analogue-to-digital conversion or sensor calibration in embedded designs.
Behaviour under continuous operation
The passive LM4040 topology maintains its specified voltage without active regulation, so output accuracy depends on the load current staying within the device’s rated range. Extended operation at elevated ambient temperatures will increase drift, so the module suits applications where the thermal environment is controlled or the error budget accommodates the temperature coefficient.

Questions about this item
How much power does the LM4040 module draw when running continuously?
The LM4040 reference operates with very low quiescent current, typically in the microampere range, so heat and power draw remain negligible during all-day use.
What external components are required to use the 2.048V and 4.096V outputs with a microcontroller?
You need a microcontroller with an analog-to-digital converter or comparator input, plus a suitable supply voltage and decoupling capacitors for stable operation.
