Part Number: INA226
Other Parts Discussed in Thread: INA3221

One of Our design required 8 CH current monitoring circuit required.

INA226 device fulfill the single channel requirement, Similar we need 8CH device TI has any such.

We can not go with INA226 8 Nos because we don't have space in PCB.

Can you suggest 8 CH Current monitoring device with SPI or I2C interface.

Thanks and Regards,

Ganesh V

    Hello Ganesh,

    Unfortunately we don't have a digital part up to 8-channels. Currently, the highest channel digital current sense amplifier we have available is the triple channel INA3221. We do have 4-channel analog CSA's so you'd only have to use 2 to accomplish your 8 channels. Is there any option of changing from your digital design to accommodate an analog amplifier?
