  • RE: LMH6626: LMH6626 Output in non inverting mode

    Resolved
    Hi Gavi, your input signal is much too large! 2Vpp x 9.52 = 19.04Vpp! Also, the output of LMH6626 cannot fully reach the supply rails but stays about 1V away from them. So, an output voltage swing of 8.8Vpp is absolutely normal with a +/-5V supply…

  • RE: LMH6626: Oscillating When Input Left Open and Sometimes When Not

    Hi James, In your current circuit, not connecting the SMA connector at BB_IN will configure the 1st stage LMH6626 in a closed loop gain (Av) of 1. The LMH6626 is only stable for |Av| > 10, which is why you see the circuit oscillating without anything…
