INA225: Input high and low thresholds of Gain select pins GS0 and GS1

Rong Guo

Part Number: INA225

The datasheet says connect pin GS0 and GS1 to either VS or GND. However, the pin descriptions show they are digital input pins.

Do they have input high and low threshold voltage specs?

For example, if VS=5V, will the gain select function still work if GS0 and GS1 are connected to external 3.3V instead of VS?

Hi Rong Guo,

Yes, the INA225 digital inputs have high and low threshold levels. You can find this information in Page 6 of the datasheet.

The gain select function will still work if the pins are connected within the thresholds.
