INA219: used on wide range power input

Shu-Cheng LIN

Part Number: INA219

Hi Sirs,

Sorry to bother you.

Could you double check if IN219 can be used on wide range power input(12V~24V)?

Because Intel got an information shows INA219 only can be used on fixed voltage input, otherwise the accuracy will be very poor.

Hi Shu-Cheng,

Can you elaborate what you mean by “wide range power input(12V~24V)”? Maybe you can provide a sketch to quantify it? If the bus voltage resembles a PWM waveform, then yes it will affect the accuracy, especially if the frequency is high.

Regards, Guang
