Part Number: INA219 Other Parts Discussed in Thread: INA3221 , INA236 , INA228 , INA229 Dear Engineers
I am currently faced with the task of building a current meter that meets specific requirements. Since this current meter is supposed to cover many channels…
Part Number: INA219 I'm looking to measure the current into a piezo element where the applied voltage could be +ve or -ve (wrt gnd). The voltage applied to the element is a triangular wave that could swing from -20 to +20V; typically it would be -20 to…
Part Number: INA219 I've developed a device with multiple chips exchanging on I2C bus. Seven INA219 are connected to this I2C too. I also connected LED display to the bus. At start, all works perfect. Currents and powers are measured properly. The problem…
Part Number: INA219 Dear Ladies and Gentlemen,
I am just getting into the workings of the INA219, but am having trouble understanding the function of the Calibration Register and how it works in general.
if I understand correctly, I can select a full…
Part Number: INA219 Hi Experts, Good day.
Our customer s trying to read a very small current using INA219 on my customized board. The R shunt value is fixed and they do not have the provision to change it. R shunt value = 2ohms maximum expected current …
Hey Tony,
The default value for the calibration register is 0, and the calibration register does need to be programmed before the registers will update, per the datasheet:

Part Number: INA219 Hello,
I'm using an EFR32BG22 host from Silabs and I wrote a driver to communicate with the INA219 with a lot of inspiration from the Adafruit driver for Arduino.
It seems I'm able to write, because the INA219 is acknowledging…
Part Number: INA219 Other Parts Discussed in Thread: INA226 , INA220 , INA230 , INA233 Hi,
My customer is looking for P2P compatible 2'nd source for INA219 and INA226 respectively.
Could you please give my some suggestions, thanks.
Part Number: INA219 Hello Community, I'm using the current sensor INA219 with NRF5340dk. Communication is through i²c protocol and using nrf SDK v1.8.0 . I'm trying to get the data output (Bus, Current, Power). i worked on the sample linked on…
