Dear Takao,
Gain error is an attribute that is inherent to the part, i.e., the INA270 has a typical gain error of .2%. Also, what type of shunt resistor are you using? This has the ability to greatly impact the system as well. If the +/- 2% error value…
Achref,
With a 27V common-mode the INA212 will not work since its maximum Vcm is 26V. There are three alternative parts that meet the Vcm>27V and have a gain of 1000x: INA139, INA282, and LMP8645. The INA139 and LMP8645 have adjustable gains, but their…
Dear Kuramochi,
I am looking at this with my team right now and will get back to you with a recommendation. Thank you for all of your information.
What is the common-mode voltage (Vcm) of your system? Basically since this is a high-side application…
Hey Lenin,
1. What limits sensing a certain di/dt is mostly the slew rate of INA193.
2. The part can accept a common mode voltage (votlage at Vin+, Vin- with respect to INA193 GND pin) of 80V. So this is fine, but keep in mind that if the difference…
Ben,
The difference between Version A and Versions B and C are the internal ESD protection diodes and their structure. The internal component of the Version A device that will latch up during a high-voltage transient is not present in the B and C versions…
Vasanth,
Please correct me here, but is your high-side/common-mode voltage +48V or -48V? Just so I'm clear.
Anyway, I would recommend a shunt resistor of 16.2 mOhm. I calculated this with the following:
Vs = 10V
Current = 0 to 30A
Max Vout =…
Many postings in the E2E Forum can be designated as a Frequently Asked Question or FAQ. In order for you to quickly create a system and implement a current and power sensing solution here is a curation of links to these FAQ postings. As time goes on more…
Hello Eli,
Thanks for your inquiry. Yes, we do have current shunt monitors that can handle a 40V common-mode voltage. They include the INA168/9 (current output), INA170 (current output), INA193-8 family, INA270-1, and the INA282.
Properly sizing…
Other Parts Discussed in Thread: INA270 , INA271 The scale of Vout(V) of Figure 17. of the data sheet of INA270/271 is mentioned with following (a) .
As for the scale of Vout(V), which of (a) or (b) is right?
(a) 0, 0.2, 0.4, 0.6, 0.8, 1.0 ....…
