Question I would like to use the ADM4073T as a current sensor for 3.5GHz HPA.
Rsense = 25mOhm
Vcc = 25-28V
Id(HPA) = 0A - 3A
1. What is the output settling time to 1% of final value for the following
conditions:
1.1. Vsense = 0V to 24mV, Vcc = +25V, VRS+ = +25V.
1.2. Vsense = 24mV to 75mV, Vcc = +25V, VRS+ = +25V. Answer We don’t spec down to 0mV on the sense voltage and this spec doesn’t change
over Vcc. So the 400ns settling time given in the datasheet would cover 6.25 to
75mV.
