Outcome

If finally, the native Vos of the TSC1031 is +1.1 mV with the current source compensation,

the equivalent input offset Vos becomes -0.9 mV. If finally, the native Vos of the TSC1031

is -1.1 mV with the current source compensation, the equivalent input offset Vos becomes

-3.1 mV.

Considering the whole application, with the TSC1031 gain set at x100 and measuring a

current of 1 A through a shunt of 0.5 mΩ, the output voltage may vary from 140 mV to

360 mV. In this case, the output of the TSC1031 (used in single supply) is never saturated.
