MAX4238/MAX4239 maximum values of input bias current (Ib) and input offset current (Ios) at +85℃ and +125℃

gattu on Sep 14, 2025

Category: Datasheet/Specs

Product Number: MAX4238

Regarding MAX4238AUT/V+ and MAX4239AUT/V+, could you please provide the following two points:

1)Could you please provide the maximum values of input bias current (Ib) and input offset current (Ios) at +85℃ and +125℃?

2)Could you please provide the typ input capacitance of them?

Hi gattu ,

Good day. Unfortunately, there were no values for the input bias and offset current for the part. Based on the TPC, it should be within pA range. As for the input capacitance, the typical value for CMOS op-amp should be within a few pF. Thanks.

Regards,
Gilbeys
