[Physical product verified] AD584 voltage reference V1.1

This is a voltage reference based on AD584

At present, AD584LH has been discontinued, so those shiny AD584LHs on Taobao or Xianyu are 99.9% likely to be fake!

Generally, insiders will first ask if there is an AD584LH with original characters and original feet:)

AD584 LH is currently the best. In fact, SH, JH, TH and the like can also be used, but the temperature drift is larger, and the foundation is a little worse.

This thing has 4 voltage levels, 2.5V, 5V, 7.5V and 10V, and has a brainless calibration of 3 and a half digits . After calibrating at a specific temperature with a high-voltage meter , it can be used to calibrate the 4 and a half digits .

The circuit is relatively simple. A jumper is used to short-circuit different places to obtain 4 voltages.

The input voltage is 15V linear power supply or 4 cells of lithium batteries connected in series .

The output can be hook-pin connected, and can be directly plugged into a multimeter pen or test clip.
