About Input offset voltage

Toku on May 28, 2025

Category: Datasheet/Specs

Product Number: LT6105

Hello team,

I understand that when using the LT6105I and the -IN voltage is within
the range of 0V < V(-IN) < 1.6V, the input offset voltage falls within
the red-framed range in the table below.

Could you please confirm if my understanding is correct?

Best regards,
Tsuyoshi Tokumoto

Hi Toku,

Good day. The -IN voltage should be within the input voltage range, Vs+,Vs- which is within -0.3 to 44 V. It is not affected by the input offset voltage. Can you clarify where did you get the -IN voltage range? Thank you.

Regards,
Gilbeys

Hi Gilbeys-san,

Thank you very much for your prompt reply.
　
　Based on the following information in the datasheet,
　 I understood that the input offset voltage may vary depending on
　the -IN voltage range:

　①The graph on page 6 of the datasheet.

　②The description in the “THEORY OF OPERATION” section on page 12.
　③The explanation in “The Two Input Stages Crossover Region” on page 14.

　Is my understanding incorrect?

Best regards,
Tsuyoshi Tokumoto
