LF353: input offset voltage of LF353D vs LF353M

Part Number: LF353
Other Parts Discussed in Thread: TL052, TL072H,


I would like to know if there is any difference between LF353D and LF353M in terms of input offset voltage.

The input offset voltage specifications from datasheets seems to be the same for the two products. But in the LF353M datasheet there is a reference to the use of 'BI-FET II technology' for the internally trimmed input offset voltage.

I'm asking this question because I'm experiencing some input offset voltage differences between some old National Semiconductor LF353M op amps and some new Texas Instruments LF353D; I've done some tests on these devices and the latters (LF353D) seems to have a input voltage offset typically greater than for LF353M (National Semiconductor).

I would like to know if switching to Texas Instruments LF353M op amps can help me to reduce the input offset voltage behavior.

Thank you.

  • Hi Nicola,

    what input offset voltages do you observe?


  • The LF353-N (i.e., LF353M/NOPB) is the same device as the old LF353 from National Semiconductor. In theory, it should have the same properties, including the offset voltage distribution. In practice, only the min/max datasheet limits are guaranteed, and the LF353-N and LF353 have the same 10 mV limit. If you care about the offset voltage, use a device with a better guarantee such as the TL072H or TL052.
