INA2180-Q1: Level shifter

Part Number: INA2180-Q1
Other Parts Discussed in Thread: INA2180

Hi team,


Good day.


Can we use one channel of the INA2180-Q1 as a level shifter from 3.3V to 5V? Do we have a sample circuit configuration?


Thank you in advance for your help.


Regards,
Carlo

    Hey Carlo,

    I am not sure what you are referring to. Are you asking if a channel of the INA2180-Q1 can independently shift a current signal from a 3.3V bus, into a voltage output signal with a full-scale range of 5V? This would be a perfectly valid use-case, that is if you need to sense a current signal through a shunt resistor.

    In this scenario, supply voltage (Vs) is 5V, the input common-mode voltage at input pins to a single channel of INA2180 is 3.3V (the VCM for the other channel can be anything between the Absolute Maximum ratings). The output (Vout) would be a voltage that is gained up input voltage with full-scale range of just under 5V due to swing to rail limitations.

    Sincerely,

    Peter
