Hi !

I would like to know, because I didn't find the info in the DS (maybe I did'nt read it right), what's the max consumption of the AM26LV31 and the AM26LV32 at 3.3Vcc ?

Thanks !

    Hi Axel,

    So I am going to preface by saying - we only spec max no load current - any additional power usage is determined by loading and data-rate which we don't directly spec. The Receiver is basically just the no load current + logic output currents (which generally are low)

     - 32 device (RX)

     - 31 device (Driver)

    This is going to be the max current consumption - with no load - as Output current is also going to be derived from ICC. For power approximations we also give a CPd value which can be used to approximate power usage with load.

    If you are concerned about max dissipated power - you just need to keep the junction < 150C where TJ = TA + R_THETA_JA * P_tot - under most conditions if you follow the ambient temperature guidelines you don't really need to worry about exceeding this value. One thing to note is that R_THETA_JA is apt to change dramatically depending on system implemented so its essentially a baseline to work with but the real effective value.

    Best,
