Hello,
No, as Kai tried to explain the INA3221 works by oversampling, the sampling frequency of the ADC is 500kHz the decimating and noise reduction filter are there to reduce the noise associated with making the measurement.
As Kai also mentioned there…
Part Number: INA3221 Hi,
We have some problem in writing to the registers of INA3221 chip. W e have tried writing to the registers, first we wanted to change the operating mode by writing to register 0x00h, but when we read back it is still the default…
Part Number: INA3221 Other Parts Discussed in Thread: INA226 After consulting the INA3221 and INA226 Datasheets, I have come up with the comparison table below:
INA3221
INA226
Shunt LSB Step Size

Part Number: INA3221 Dear Sir,
we design INA3221 with Input Filtering, should we place R_Filter and C_Filter near INA3221 Input channels, or place near shunt resistance(Sometimes shunt resistance is far away from INA 3221) ?
Part Number: INA3221 HI:
MCU communicates with INA3221 through IIC, and the customer needs the reference source program of MCU,
Or help to confirm that the reference source code is this?

Part Number: INA3221 Hi experts,
I see INA3221 have SMBus Alert Response function;
Can we combine the four Open Drain output pins of Critical/Warning/PV/TC into one signal to the master, when any event occurs, the master can locate the specific INA3221…
Part Number: INA3221 Hi there,
I am trying to create a system which needs the highest possible sample rate.
In my understanding, the conversion time, averaging length & number of channels are all factors into increasing the INA3221 loop time.
INA3221…
Part Number: INA3221 Team,
Can we apply a voltage to VPU such as 5v or 3.3v and pull up the PV and other status lines to lower voltages such as 2.5v, 1.8v, 1.0v…. The data sheet has it being pulled up to VPU and we would like to pull the open drain status…
Part Number: INA3221 Hi Team,
My customer is searching for a multi-channel power monitor device. I found INA3221 but I am not sure if we have any other similar device? Thanks.

Part Number: INA3221 Dear team,
I am looking for 12Vin/200A current monitor solution, below are device feature we need.
> Dual channel, and each channel can support 12Vin/200A
> Digital interface, I2C will be better
> No need to monitor voltage…
