Hello,

What is the input impedance on the TLV9054 opamp? The datasheet does not mention this.

Thanks

Hi Eben,

as the input bias current of TLV9054 is in the pA range, the DC input impedance is in the 100...1000GOhm range. See also figures 6 and 7 of datasheet.

At higher frequencies the input impedance is dominated by the input capacitances.
