INA226: Looking for Similar Components with Additional Features

Part Number: INA226
Other Parts Discussed in Thread: INA3221

I have a client looking for something similar to the INA226 features ( I2C capable/16bit resolution ) but I needed more features listed below:

  1. 16bit resolution.
  2. Bus voltage can read 100V max ( if none, 40Vmax is okay )
  3. >2 channels, I need 3minimum channels.
  4. High impedance input.
  5. Has reset capability.
  6. 3.3V supply.

Or can you recommend something similar to LTC1859 ( but I need high impedance Mux input ) with the following features

  1. 16bit resolution.
  2. MUX input channel can accept >10V
  3. =/>4 channels.
  4. High impedance input.
  5. Has reset capability.
  6. 3.3V supply.
  7. I2C/SPI capable

Thank you for helping me.

    Hi,

    Regarding the first request – we don’t currently have a device that satisfies all the requirements. INA3221 is the closest with three channels, however it falls short on Bus voltage (26V). You can browse our current/voltage/power monitors here for further information.

    Regarding the 2nd request – experts in data converters will provide recommendations shortly.

    Regards, Guang

    Hi,

    Sorry for the inconvenience, but regarding the LTC replacement - could you please make a separate post to the Data Converters Forum?

    Colleagues there will take care of you. Meanwhile please close this thread if you have no further questions regarding current sense amplifiers.

    Regards, Guang
