Part Number: INA219

Dear Team,

Can this device sense AC input voltage and AC input current?

If not, do you have a suitable solution in your product line?

Hi Kevin,

It can measure certain AC inputs, but not all.

It will be helpful if you could define the inputs with more details, through key parameters such as shape, amplitude, frequency and DC offset.

Dear Guang

It is for:

Sine wave

No DC offset

Voltage -> 97~264VAC

F = 47~63Hz

Current => 5A

It doesn't need to be precise for the measurement, use the voltage divider is ok.

Hi Kevin,

INA219 will not be able to measure the given AC input. However please look into TMCS1100 and TMCS1101. They seem to offer an ideal solution, though both are voltage output.
