AD584 Voltage Reference Kit

A good electronics laboratory needs references.A good home laboratory needs cheap but “good enough” references. I needed a voltage reference, and found out cheap kit: 3pcs AD584 4 Channel 2.5V / 5V / 7.5V / 10V High Precision Voltage Reference Module costs less than 10 Euros.  This device is AD584 based 2.5V / 5V / 7.5V / 10V high precision voltage reference module. It can be configured to output any of those voltages by moving a jumper. This is one of those cheap AD584 based voltage references:

The AD584 is an 8-terminal precision voltage reference offering pin programmable selection of four popular output voltages: 10.000 V, 7.500 V, 5.000 V and 2.500 V. The input voltage can vary between 4.5 V and 30 V. The input voltage needs to be higher than the output voltage setting (at least 1.5V higher), so I decided to test the device with 12V DC input voltage that is enough for all voltage settings.

Results when I powered the device from 12V dc power source show that the device seems to be pretty accurately match my most accurate multi-meter:

I got three devices. Two were this accurate, third was a little bit more off, but still very accurate:

Very accurate! I this this3pcs AD584 4 Channel 2.5V / 5V / 7.5V / 10V High Precision Voltage Reference Module kit is well worth of the small price paid. Next task is to mount them to some suitable case.

 Addition: Measurement with more accurate meter those that showed accurately 10V (+-1mV) on multi-meter.

    Will the right voltage reference stand up?

    This is the scenario. You have a good idea about your application needs, and you have finally zeroed in on the correct analog-to-digital converter (ADC). The next step is to feed the ADC with the proper voltage reference chip and driving amplifier. In this article, we will talk about how to choose your voltage reference
