Hello John,
John B said: I am wondering how can I find from datasheet that t he Vbus Impedance is 670kΩ ?
Yes, you found the right spot. It's spec'd a little different in this datasheet than we usually spec it, but that is the location. The VBUS is measured…
Part Number: INA3221 Other Parts Discussed in Thread: INA4230 , INA4235
Tool/software:
Using this part, sometimes it is difficult to place the monitor close to the current/voltage source you wish to monitor, especially with a 3 channel device such as…
Part Number: INA3221 Other Parts Discussed in Thread: INA4230 , INA4235 Tool/software: In our implementation, referring to Figure 26 of INA3221.pdf, March, 2016 edition, “INA3221 with Input Filtering”:

Part Number: INA3221 Other Parts Discussed in Thread: INA901-SP Tool/software: Hello,
I would like to have voltage, temperature and current monitoring solution on the PCB which is under development. The voltage level is 3.3V. The temperature range is…
Part Number: INA3221 Other Parts Discussed in Thread: INA4230 , INA4235 Tool/software: I'd like to monitor a 24V line.
Vbus is specified 0 - 26V. I would normally give some margin of error on the 26V. Is there some margin built in to the specs of the…
Part Number: INA3221 Hi Team,
Customer have 2 questions about INA3221.
1. What's the Vgsth of PV open-drain output MOSFET?
2. What's the output type of Power valid detection? Vpu used as push-pull power supply or pull up of another open-drain output…
Part Number: INA3221 Tool/software: Hi All,
I have a question about the INA3221. I am measuring a shunt voltage with a target range of 0V to 0.5V, but the result I am getting is about 0.2V higher than the actual value.
When I measure the voltage across…
Part Number: INA3221 Hi,
I'm using INA3221AIRGVR in my R&D project with all 3 channels connected as following:
- CH1 -> track 5V
- CH2 -> track 1.8V
- CH3 -> track 3.3V
1. For VPU, I connected it to VS (3.3V). Therefore, can PV (Power…
