INA290: No Output Voltage

Part Number: INA290

I have set up a circuit with the INA290. Unfortunately I have no success.

I need to be able to get a battery charge of roughly 4A / 80A discharge over 1 mE.

I want to use the INA290A2 to measure the discharge current.
And for the charging current the type INA290A5 via the same shunt resistor. For the second channel, I changed the direction from the input positive to negative. So i will have two positive voltage to an ADC-Inputs on my Microcontroller.

But i have no voltage on the output pin (INA290) and i can't found an error or mistake in my circuit.

Supplyvoltage is 5V-Positiv.

  • Andreas,

    Thanks for choosing TI! When you say you're not getting any output voltage, is this for both devices, or just one of the two?

    Can you post a picture of your schematic please?

    Also, can you probe the differential input voltage at the pins of the device with a scope, as well as the output voltage? This might help us understand a bit better whats happening.
