TLV6741: input impedance?

Bruce li

Part Number: TLV6741

Dear TI Experts,

May I know the input impedance of TLV6741? I can't find this parameter in its datasheet. Could you kindly help to advise? Thanks a lot.

Hi Bruce,

the input resistance is negligible. See figure 7 of datasheet. So, the input impedance is "dominated" by the 6pF input capacitance.

Hi Bruce,

The input resistance is very high for CMOS amplifiers. I think this forum thread may help you.

Thank you,
