The 100 µV input offset voltage and 80 µA input bias current are typical for a general-purpose current sense amp; for sub-milliohm shunts or microamp-level sensing, a zero-drift type like the INA254A1IPWAR would be a better fit.
The gain is set internally by the device variant — the INA180B1IDBVT is a fixed-gain version. The exact gain factor is specified in the datasheet; the part number suffix indicates the gain option. For a different gain, select the corresponding INA180x variant.
The INA254A1IPWAR is a zero-drift current sense amplifier with the same 350 kHz bandwidth and similar supply range, but lower input bias current. It is a functional alternative for precision applications, though the package differs.
