LMP8480-Q1: about input bias current

Part Number: LMP8480-Q1

Hi team

i need lowest input bias current for low power consumption.

LMP8480-Q1 D/S says Max 12uA per input.

may I get your reply ?

[1] so total input bias current will be 24uA(=12uA x 2) ?

[2] at VCC = 0V, may I know Max Input bias current at common mode voltage = 20V ?

    Hello Paul,

    Thank you for your interest in our LMP8480-Q1. The input bias current in the datasheet corresponds to the average value for both inputs, so the max will be 24uA for VCC = VRSP = 76 V
    For this device architecture, we expect the input bias current to basically be 0 for Vs=0V.
