You should use a ready-to-use current sensor that are made for high/low side detection. Anything else makes life more complicated.
Examples: AD628, AD8417, ADM4073, AD8418A, etc. etc.
Let me see whether I can find some resources that you can use. In the meantime, you might want to take a look at the AD8417. It is similar in architecture to the AD8418, but it has a gain of 60, which will allow you to use a smaller shunt…
Yes you can measure current with AD8293.
You can also use AD8417/AD8418 which is specifically designed for current sensing applications. This has high CMRR and low input offset which is necessary in current sensing.
Specifically I'd need to adjust output to +1V when Vs is +3.3V.
I would do this by tying Vref2 to GND, and pulling Vref1 to +3.3V with ~120k resistor. Assuming 100k internal resistor in Vref1 and Vref2 that should work, but does it lead to noise…
I have some questions about ADI datasheet.
Our team are checking the datasheet because if the datasheet was changed we have to explain the changes.
And today , we found many datasheet was changed.
For just one example , AD8206 datasheet was changed…
I would like to know how to use current sense amp in PWM motor drive system.
For example, AD8418 has a peak output by input common-mode step response.AD8418A,AD8417, AD8210 .... also.(see AD8418 datasheet Fig.18)
These noise are tough to erase…
Oh. So your question really was "The AD620 is spec'ed for +/-15V, can I operate it on ground and +24V??"
Here's a snippet from a recent email to another customer regarding op amps, but it also applies to InAmps:
"We get this type of…
