Hi wang.zhen.003,

For most of ST operational amplifier product the A label define a product with a better Vio.

You don’t have any difference one the DVio/DT = 7µV/°C in typical value or 30µV/°C for max value in the both cases.

If you compare the max Vio value between LM224 and LM224A you can see a difference of 2mV.

Ambient:5mV -> 3mV(A version)

Temperature:

7mV -> 5mV(A version)
