INA301: To understand Gain error of the amplifier at different load conditions

Part Number: INA301

Hi Carolus,

We have tested the boards and the output of the INA301A1 is 0.859V at the load current of 10A but it should have been 1V as per the datasheet and the

formula(10A x 5 mΩ x 20 V/V =  V).

As per the datasheet of INA301A1 below are the expected results from the INA301A1,

Sl.No load Current(A) Expected INA301A1 output(V)
1 0.5 0.05
2 1 0.1
3 1.5 0.15
4 2 0.2
5 2.5 0.25
6 3 0.3
7 3.5 0.35
8 4 0.4
9 4.5 0.45
10 5 0.5
11 5.5 0.55
12 6 0.6
13 6.5 0.65
14 7 0.7
15 7.5 0.75
16 8 0.8
17 8.5 0.85
18 9 0.9
19 9.5 0.95
20 10 1

Please do the needful.

Thanks,
