  • LMH6518: AV_DIFF_MAX & ZOUT_DIFF meaning

    Resolved
    Part Number: LMH6518 Hello, In the LMH6518 datasheet, I am reading that AV_DIFF_MIN or AV_DIFF_MAX have about +/-0.7dB gain variation. I can also read that the ZOUT_DIFF variation is +/- 8Ohm. The voltage divider made of ZOUT_DIFF and differential 100Ohm…

  • LMH6518: VCM_Aux input when auxiliary output amplifier is not used

    TI Thinks Resolved
    Part Number: LMH6518 Hello, We use the LMH6518 with the auxiliary amplifier turned off. The complementary auxiliary outputs are left floating as well as the VCM_Aux input pin! Is this correct or should we somehow bias the VCM_Aux input? Same for the output…

  • LMH6518: Power Down 5V only

    TI Thinks Resolved
    Part Number: LMH6518 To save power, customer would like to power down analog 5V when signal chain is not in use, but leave 3.3V applied to VDD (digital). Is this OK? Data sheet doesn't seem to mention power sequencing that I can see.

  • LMH6518: Question on clamping function

    Resolved
    Part Number: LMH6518 Hi team, My customer is looking at using the LMH6518 but has a question. Our understanding on the over-voltage clamp is it gives you the ability to set a max/min output voltage level. They do not need this function, but want to know…
