Hi team，

what is the input resistance of tl082h？we can not find it in datasheet.

Thanks

You can compute a resistance value by dividing the input voltage by the input bias current.

But the inputs of CMOS opamps do not behave like resistors. The input bias current specification itself usually is more useful for designing the circuit.

Hi Victor,

For the TL08xH, table 6.11 Electrical Characteristics has the Input resistance (differential and common mode)

Please let me know if you have further questions.
Thank you!

Best Regards,
Ashley
