Part Number: INA223 Hi Team,
Please kindly help to confirm the Vout calculation and sch.
Our setting as below pic.
And the calculation as below:
Rsense=0.001 Ohm , current at 278W/12V=23.167A Vsense=1m Ohm x 23.167A = 0.023167V INA223 Vout =(DC IN) *…
Hi Sreenivasa,
Thanks for getting back to me. The single supply requirement is not that critical, but it would help simplify the design a bit.
The main goal is to create a constant power (heater) circuit that also has a temperature sensing capability…
Part Number: INA223 Other Parts Discussed in Thread: INA233 Hi~
May I know the minimum load resistance at VOUT pin?
According to datasheet, its electrical characteristics is based on RL= 10Kohm.
Thanks,
Tiger
Hi Andrew,
From the earlier posts of this thread its suggested that we can read this device through simple i2c tools and also with the linux driver.
But from the latest posts from you gives that we are not in right direction to access this device.
At…
Hi Kai
Thanks for recommendation!
Noise is everywhere; Other than Lab, I should move all the setup to another quite room (we have no dedicated chamber, meeting room may be suitable) and keep away from any electronic devices
Due to difficulty of the…
Part Number: INA223 Hi Sir
According to table in Page 4, output impedance of INA223 is 4 ohm typically
Since it names as impedance, should it be AC term?
I cannot find any description more in the datasheet.
Is it possible to take a measurement to confirm…
Part Number: INA223 Hi Sirs, Was IB specification in the INA223 datasheet specified by Vin = 0V? Would you pls manage IB vs Vin's curve (or equation) thus we can calculate the RF impact for customers? Thank you and Best regards, Wayne Chen 01/15/2018
Part Number: INA223 Hello Patrick, Addition to the thread at INA223: Need INA223's IB vs Differential Voltage's Chart
With the concept on the left, can I say that the IB+ ramps from 0uV to 25uA as differential input voltage increasing, and the IB…
Part Number: INA223 Hi Sirs, According to the INA223 datasheet, there is only one configuration register thus there should be only three data frames for I2C write. Would you pls advise if the frame 2 register pointer byte a mistake and should be removed…
Hi Joyce,
Unfortunately all of our power monitoring devices require some type of I2C communication to change settings and configure. However, we do have the INA223. The INA223 is an analog out device, which is I2C programmable for certain settings. If…
