    Hi d.,

    TI does have alternatives to the parts use listed. We have a cross reference tool (found here) that will point you to equivalent TI devices.

    For TPF140: TI offers THS7372 which has the same functionality

    For TPF130: TI offers THS7316 which has the same functionality

    For TPF110: TI offers OPA360 which is a pin-for-pin replacement or the OPA361/OPA361-Q1

    Do you need the video amplifier to be automotive qualified?

    Thanks,

    Nick

    Hi Nick,

    we don't need automotive qualification. Can you tell the key difference between OPA360 and OPA361?

    Best Regards,

    Hi d.,

    From a performance perspective, the OPA360 operates at an internal gain of 6dB while the OPA361 operates at and internal gain of about 14dB. Also, OPA361 has a lower quiescent current (5.3mA vs 6mA typical).

    The OPA360 also has an internal sag correction circuit that is used to decrease the size of capacitor needed to achieve this externally. This is talked about in more detail in this E2E thread (here).

    Thanks,

    Nick
