Hello,
I am having an issue with LM4051-ADJ.
I attached my simulation in PSpice with included equation from datasheet and their results.
Link to the model I used in my simulation.
LM4051_ADJA1P212 Unencrypted PSpice Transient Model
Information form datasheet:
Link to the datasheet:
LM4051-N Precision Micropower Shunt Voltage Reference datasheet (Rev. D) (ti.com)
For assumed values:
R1 = 10k
R2 = 42.2k
The result of the equation included below is different from the simulation result.
I noticed that if the resistors in equation switch place (V0 = (1+R2/R1)*Vref) I received the result that match my simulation.
I think there are two possible reasons:
- There is a mistake in datasheet
- The model is not correct
Could you please give me insight into this matter?
Thanks,
Alen
