BUF634A: THD+N Value

Part Number: BUF634A
Other Parts Discussed in Thread: OPA1656, BUF634, OPA1642,

Hi team,

What is BUF634 THD+N at 1kHz? I see the HD2 & HD3 values but do not see a THD+N value like I do in other op amp datasheets (such as the OPA1642 or OPA1656).

Thanks,
Sarah

    Hello Sarah,

       Unfortunately, I was unable to find any internal testing for THD+N for the BUF634A. Section 9.2.2 in the BUF634A datasheet reports the THD+N value when the BUF634A is used within a composite loop.

        For our high speed amplifiers, we focus on the main contributors to the THD+N specification which are HD2 and HD3, and their values over a wide range of frequencies, loads, and output voltages. We report a wider range of distortion specifications (including THD+N) for our audio and precision amplifiers.

    Thank you,

    Sima
