TLV9061: ZO Open-loop output impedance

Part Number: TLV9061

Hi Experts,

According to TLV9061 datasheet, ZO Open-loop output impedance has typical value of 100Ω.

My customer needs to know the ZO Open-loop output impedance MAX/MIN value at

1. 25-60℃

2. -20-85℃

Do we have this value to provide?

thank you.

    I think manufacturing tolerances of up to +/-20 at 25°C are realistic.

    Hello Lin-san,

    You are correct in that the open-loop output impedance is not typically specified across temperature. Generally speaking, any variation in this specification should be covered by proper design margin. If given enough margin, your customer should not have issues with stability, for example.

    A good margin would be +50%/-33%. +100%/-50% would be even better.

    If you are comfortable with doing so, you can post your schematic here and we can help with simulations.  This may convince the customer that their design is safe.

    Regards,

    Daniel
