OPA2172QDGKQ1

Will the characteristic parameters (bandwidth, voltage swing rate) of OPA2172QDGKQ1 be changed with the output current (load)?For example, as the load increases the characteristic parameter decreases?

    Meng,

    The voltage swing rate (slew rate) is set internally and load current or load resistance will not have an effect.
    Bandwidth could be affected. The internal output impedance and load creates a voltage divider.
    The typical Zout is 60 ohms so the reduction should be minor.
