Part Number: INA194A-Q1 Other Parts Discussed in Thread: INA293 , INA194 , INA290 , INA281 , INA280 Please let me know if there is accuracy better than the INA194AQDBVRQ1. Also, if there is an isolated current amplifier that is inexpensive and has good…
Hi Kevin,
Thanks for considering the usage of the LM5176 in your design. In the application note attached, this was implemented by simply tying the two outputs of the LM5176EVM together with an external circuitry using two INA194.
There is another…
Hi Ivan,
Please refer to the thread: https://e2e.ti.com/support/motor-drivers/f/38/t/355575 . We have not performed any additional studies so the recommended upper limit is still 200kOhms.
The DRV8412 and DRV8432 have similar specifications.
Have…
Hi Rick Duncan
Good morning,
Regarding 3rd point, i have one doubt i.e
3) How to ensure this device is working in forward braking and reverse braking quadrants. How to test or monitor the current during that time. Any application note?
>>> Monitoring…
Part Number: INA194A-Q1 Other Parts Discussed in Thread: INA194 hi there,
my customer wonders which maximum values for the Analog Inputs, Vin+ Vin- on INA194A-Q1 apply. the datasheet of INA194 lines out -18 to +18V ; in the datasheet of INA194A-Q1 this…
Other Parts Discussed in Thread: INA193 , INA194 Hello,
My customer uses the INA193 or the INA194.
When monitoring power supplies, that are switch off briefly.
That is Low Vsense Case3.
He wants to know the output behavior of the device.
Do…
Hello Evan,
Thanks for posting to the forum. The short answer is yes this behaviour is expected. The zero-current output voltage (VOUT) for INA195 can be quite high, espcially when Vsense≤20mV and 0V≤VCM≤VS. For this scenario we spec the VOUT for INA195…
Hello Kuramochi-san,
This typical spec for full-scale input voltage is not actually very useful. The 0.15V shown just gives the user an idea of the typical range of input voltage for these devices. For example, 10A of current through a 15mΩ shunt would…
Hello Peter and Michael,
Thanks for your replies.
I'm waiting on some ordered components to test your proposed solutions. I'll continue on both ideas. Either working with current sense amplifier (INA240, INA186 and INA190 ordered). And on the other…
