I use LM336 Diodes for 2.5V voltage regulation as the reference voltage of the DA chip. However, the voltage will decrease continuously over time (the amplitude is not large, about 0.00), and the voltage will also change before and after the circuit is connected to the microcontroller.
I Want to ask how to solve it? I just connect a resistor directly through 5V and then V as in the chip manual. Is the circuit too simple, how can I improve it?
