TLV342S: Input impedance at shutdown mode

Part Number: TLV342S

Hello support team,

I have a question about TLV342S.

A question
1. I think that the input impedance of the TLV342S hardly changes between with normal operation and at shutdown mode. (keep high impedance).
Is my understanding corrent?

Best regards,
M. Tachibana

  • Tachibana-san,

    Yes, you are correct.

    Hello Michallick-san,

    Thank you for advising me.
    I understood.

  • In reply to Ron Michallick:

    Can I know the values for the input impedence under the shutdown mode ?

    Thanks

    Alessio,

    Input impedance is set by thermal diode leakage (current source) and input capacitance (about 5 pf, estimate)

    I have a leakage vs. temperature chart for Nominal, Weak and Strong (process experiment) samples
