Description
Common Connection. Connect via low impedance to system common.
Input HPF. Connect to common via a capacitor to determine 3 dB point of input signal high-pass filter.
Decoupling Terminals for INHI and INLO. Connect to common via a large capacitance to complete
input circuit.
Differential Signal Input Terminals. Input Impedance = 200 Ω. Can also be driven single-ended, in
which case, the input impedance reduces to 100 Ω.
Disable/Enable Control Input. Apply logic high voltage to shut down the AD8362.
Connection for Ground Referenced Loop Filter Integration (Averaging) Capacitor.
Analog Common Connection for Output Amplifier.
Setpoint Input. Connect directly to VOUT for measurement mode. Apply setpoint input to this pin for
controller mode.
RMS Output. In measurement mode, VOUT is normally connected directly to VSET.
Connect to 5 V Power Supply.
The logarithmic intercept voltage is proportional to the voltage applied to this pin. The use of a lower
target voltage increases the crest factor capacity. Normally connected to VREF.
General-Purpose Reference Voltage Output of 1.25 V. Usually connected only to VTGT.
