Part Number: INA228 Tool/software: Working with an INA228. I am wanting to accurately sync the conversion with a PWM signal.
I am seeing an unexpected short delay when carrying out 1-shot triggered measurement of VBUS. In the trace below, the red trace…
Hello Pelle,
Sorry for the delay in this thread, I'll be taking over the support.
For your question:
Pelle Lund said: So that means that the TCA9406 should not be used with INA228?
It's hard to say, because the datasheet for the TCS9406 says it needs…
Part Number: INA228 Tool/software: I am using the SCB controller to talk to the INA228 that I have on my board (via I2C) by wiring the SCL, SDA, 3.3V and GND from the INA228 to the SCB. I use the same GUI as the eval board. I set the address SW0 and…
Part Number: INA228 Tool/software: Hello,
If VBUS is 60V, we are not sure wheter the leakage current will be the same if 3V3 supply is missing?
Best regards, Miroslav
Part Number: INA228-Q1 Hello
I use INA228-Q1 IC in the circuit board I designed. I take low side bi-directional current measurement and bus voltage measurement via IC. I can read the current and voltage values correctly via the software. I want to use…
Part Number: INA228 Tool/software: Hello,
With our INA228, we’ve been using shunt resistors with 4 pins designed for kelvin sensing like RES SMD 1 OHM 1/2W 2516 WIDE.
Example Y08501R00000F9W - $12.82 each
What is the consequence of using a wide…
Hi Jagir,
The offset of 1uV means the error could be up to 100% when the device measures a 1uA load current over 1Ohm. This error gradually reduces (% accuracy improves) as load current increases.
Offset is not resolution.
1uA to 40mA is too wide a range…
Part Number: AWRL1432BOOST Other Parts Discussed in Thread: AWRL1432 , INA228 Tool/software: Hi Expert,
INA228(current monitor) is connected AWRL1432 in AWRL1432BOOST.
Could you tell me how to confirm / read the value of INA228?
Is there any tool to check…
Part Number: INA228 Tool/software: Hi team,
Below is my customer's sch. The current sense voltage is 30V and the VS bus voltage is from 10V, which is divided from 30V. So, the 10V and 30V is from the same source but has different level. Could you please…
Part Number: INA228 Tool/software: Hi team,
Could you please help to evaluate whether the INA228 can measure the square waveform as below? The frequency is 90Hz.
Best regards,
Rannie
