INA238: Pull up and pull down resistors on Address pin

Naizeng Wang

Part Number: INA238

Hi team,

Can we connect Address pin directly to GND or VCC? Or we must put pull up and pull down resistors? How about the value of resistors?

As shown in figure 8-2, a direct connection is allowed.

Nison,

Thanks for the question and using the E2E forum.

As Clemens points out, figure 8-2 does show that the address pins can be connected directly to GND or VCC (a direct connection to GND would result in an I2C address of 0x40).

Please let us know if there's anything else we can help with.

Louis
