Current measurement high side or low side advantages disadvantages

I need measure current for example 0-10A, my first idea is 5mOhm shunt resistor on low side and Zero Drift, Ultralow Noise,Rail-to-Rail Output Operational Amplifiers ADA4522.
Second idea is use 5mOhm shunt resistor on High side and INA193 Current Shunt Monitor (+80 V)
I can not decide which solution to choose and bring more advantages than disadvantages
Do you advise?

Low side shunt is simple and accurate. The usual reason to switch to high side shunt is in the application environment, like kind of load and connection requirements (e.g. common ground wanted) - beyond the scope of your question.

you can use ACS712 series hall effect based current sensor. It will be easy to use as well as easy to measure.

Often depends on what you are after. For current mode
control in a switcher, high side or inductor current sense
offers pulse-by-pulse, during-on-time control and pulse
termination (useful for things like short circuit protection).
Low side sensing only works after the pulse has turned
back off and would not show realistic short circuit current
(as that might saturate the inductor and return less than
all the IOUT, to the low side switch).

But high side schemes tend to be slow, noise exposed,
etc. and high side sensing may work out better for ICs
than for piece-parts assemblies.

A high side sense that is fed a reference current and
returns a switching event (comparator) may be better
than trying to make a continuous-time sense amp (or
Hall, via its excitation and amp chain) go fast enough
to respond right, intra-pulse.

ACS712 not bad product, unfortunately in the time of 3.3V processors and systems still requires + 5V power supply.
Which is a pity.

The ACS712 is outdated, being recommended by manufacturer to use the ACS723 instead, which brings a higher breakdown voltage.

Thank you for the information
ACS723 is good solution for +5V system , but more complicated for +3,3V system.
I'll probably use low side shunt and INA225 amplifier

Hi,

For sure you can usd an INA,
But a usual low offset Opamp that's common mode range includes GND does the job.
