Equivalent Op Amp to LT6016

Other Parts Discussed in Thread: LMP8640HV, INA240

Hi, I'm unable to find a TI equivalent op amp to the LT6016. The main feature that I'm interested in is the "Over-The-Top" input stage. Meaning that the input protection diodes will activate at a certain voltage whether the op amp is powered on or off. For example, with the LT6016, the input protection diodes will active at approximately 80V above or -25V below to Vs-. This op amp will be used for precision filters and signal conditioning. Input signal can range anywhere from 10uVp to 3mVp with a max bandwidth of 1MHz. Does a similar TI op amp exists?

Thank you.

    Hello

    In terms of our Current Sense Amplifier (CSMs) there is no complete equivalent. The LMP8640HV has a max input Vcm (common-mode) of 76V and BW of 950kHz, but its max input offset is 900uV. The INA240 has a 80V max input Vcm, but a 25uV offset and 400kHz BW and this is the best offset given the high Vcm requirment. Additionally, aside from input RC pi low-pass filters that can be added to CSMs, there is no active filtering possible since these are closed-loop devices.

    I will see if our precision amplifiers team can assist you on this.

    Hi,

    Unfortunately we do not have a part like this in our portfolio. If you are interested we can explore other discrete solutions to achieve what you are looking for, but we can't offer an integrated device at this time.
