  • LMH6881: Noise density with gain condition

    Resolved
    Part Number: LMH6881 Hello team, LMH6881 datasheet provides output noise density and input referred noise density information with maximum gain(26dB) condition only. How can we know or calculate noise density(output or input referred) with different gain…

  • LMH6881: Setting common mode voltage for 3.3V differential ADC application

    Resolved
    Part Number: LMH6881 Hello, We would like to use the LMH6881 differential output to interface to a differential 3.3V STM32 ADC. This would require us to set the common mode output voltage to 1.65V for our desired maximum range. According to the datasheet…
