I got some samples from TI.
I love those guys.

The attached data Name is what I got.

I like to clear a confusion regarding gain
It is on the first page under Choice of Gains.

I have INA199B3 : 200V/V
& INA211 and 212 which has 500V/V and 1000V/V

I was wondering what exactly it means.
AM I right to think they are
200V/V is 200 Gain and so on.

I was thinking of using them in my charger.

Which will have a max of 5 Amps.
I wanna use them to scale the Current shunt value to ADC to 5 Volts.
Haven't figure out the shunt value yet but I got two shunts from those cheap ebay Current meters.
I haven't yet measured the resistance of those shunt yet

 

No your links do not work.

Yes that is the correct gain.

No to connecting a shunt to show 5V for 5A with a 5V reference is horrible because 100 amps reads the same as 5 amps does.

Any resistor in series with the regulator output will effect regulation. A better place is before the regulator, even better is before the regulator and in the hot high side (not ground).

They are not links but pdf attached to the forum

What is correct ? about gain being 200 for 200V/V.

The PDF shows how to connect the shunts.
