LM358: output offset voltage

masaki harada

Part Number: LM358
Other Parts Discussed in Thread: , TLV9101, OPA2990, TLV9001

I would like detailed data on the output offset voltage of the operational amplifier LM358.

In the same LM358 series, there is one in which the electric circuit turns OFF in LM358D and turns ON in LM358B.

Therefore, I would like detailed data such as the voltage distribution characteristics of the output offset

(a graph showing what percentage of the offset voltage is on the positive side and what percentage is on the negative side).

Thank you.

This data is published only for the LM358B:

But for both devices, the distribution is centered near zero.

There are known differences in the behaviour of the LM358 and the LM358B, but only if you go outside the valid input common-mode range. So if this is the problem with your circuit, you should replace the LM358x with a rail-to-rail opamp like the TLV9001/TLV9101/OPA2990.

Harada-san,

The offset voltage can be either polarity, both polarities are very common and must be supported in the application. If both inputs exceed the upper common mode range, then output may be high or low and one state may more common than the other. For any input below common mode range, output may be high or low and one state may more common than the other.
