Dear Team,

please tell me at which chopper frequency OPA2392 works.

Kind regards

    HI Bernd,

    The OPA2392 is a high precision, low -offset linear amplifier.  It offers very low offset ±10 µV (maximum) and low-drift: ±0.18 µV/°C. 

    However, this amplifier uses e-trim technology to achieve the high-precision; therefore it is not a chopper, and there is no chopper frequency associated.

    Attached is an application note describing the different circuit techniques used to minimize offset in amplifiers that may be of interest:

    Thank you and Kind Regards,
