The nominal load for the ADA4431-1 is 75 Ohms.
But what are the min and max tresholds for the ADA4431-1 "load detect" function ?
In video load condition, ADA4431-1 power up from 0.1 mA to 4.7 mA.
Have you referred the ADA4431-1 product page,whether threshold range has provided for load detect function at www.analog.com/.../ada4431-1.html
Thanks for your answer.
If we look at the Table 1 page 3 of the ADA4431-1 datasheet www.analog.com/.../ada4431-1.html , the the 0.1mA correspond to the load Searching Mode.
For me, this two informations does not give us the minimal and maximal load threshold (around the nominal 75 Ohms load), but only that the ADA4431-1 drives a 0.1mA in order to detect if a load is connected.
It's not clear and maybe I wrong.
