Part Number: INA219 Hello,
When operating INA219, if we choose averaging modes for INA219_CONFIG_BADCRES and INA_219_CONFIG_SADCRES, which range from 2 to 128 averages, and if the ina219 is working on continious mode,
will it take longer time to read…

I'm trying to read both voltage and current of battery by giving some load. My battery voltage when checked with Multimeter is 3.12v but my code is giving 2.9v. Which register should I read to get current values?
Connection:
…
Part Number: INA219 I want to read only the voltage of battery connected. Below is the picture of the connections I made. Battery voltage is 3.7v but I'm getting different values every time when i read shunt voltage (0x01) register which has huge difference…
Part Number: INA219 Hi Team,
Customer would like to know the power consumption about the INA219BIDR, can I calculate it with below under 25 degree of room temperture?
Rja=111.3,
Tj= 150
150=25+111.3*Pd.
maximum Pd = 1.12W.
so the this device maximum power…
Part Number: INA219 Hi TI Team
I am designing a bus voltage monitor using the INA219 & the application requires that the INA219 draw very little current (<100uA). Hence I have been trying to power down the device whenever I don't need to take any measurement…

Hello. In the picture above you can see my circuit.
Unfortunately, I can not find a proper value for the calibration register, to have the same value as what I am getting from the Multimeter.
Thank you
Part Number: INA219 Hello,
When will INA219 be available on the TI store? Is there a replacement part that is easier to supply? It seems that some opportunistic people has driven the price to 17-18USD per ina219.
Best Regards,

Hi,
I have a INA219 connected to a Nucleo-F401RE. The address pins of the INA219 are both connected to GND. This should result in a I2C address of 0x40 if I am not mistaken. When I run a I2C scan on my Nucleo-F401RE (after setting…
Part Number: INA219 Hello,
I am using multiple INA219 devices with I2C comms.
I am able to program the calibration register and read the value back. This works well on all devices.
However, I get intermittent ZERO value reads for Current, Power, and sometimes…
Part Number: INA219 Hello.
I have problem with ACK bit from INA219. I get ACK bit after sending SLAVE_ADDRESS_WRITE ((0x40)<<1), but after sending pointer of Configuration Register or something else pointer, i dont get ACK bit.
what's wrong? …
