LM4040 Dual Voltage Reference Module

Compare suitable measurement circuits against two nominal voltage references with a compact LM4040 module.

✅ Check two reference levels - The board provides described 2.048 V and 4.096 V outputs for compatible measurement work.

✅ Keep a reference on the bench - A small module format fits into a test fixture or electronics-development arrangement.

✅ Power from a suitable low-voltage source - The normal 5-12 V input range accommodates the described reference operation.

Give the measurement a reference point

A known reference is useful when checking an ADC reading or comparing a meter's indication. This module supplies two nominal levels that can be incorporated into an appropriate low-current measurement setup.

It is a voltage reference, not a general regulated power supply for loads. Check its actual output and conditions against the accuracy required by the work; a small reference board does not replace a traceable calibration service.
