INA226: Device with less conversion time

Part Number: INA226
Other Parts Discussed in Thread: INA228, INA238

Tool/software:

Hi team, 

For INA226, the smallest conversion time is 140us. Customer think it is too long. Do we have device with shorter conversion time whereas other specs are similar or better?

    Hi Nison,

    I'd recommend the INA228 (20 bit with accumulators) and INA238 (16 bit), they're both pin to pin compatible with the INA226 and the INA238 has a conversion time of 50us.
    The INA228 has higher precision accuracy, while the INA238 has comparable precision and accuracy to the INA226.

    Best,
