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.
High Signal Input Terminal. Part of a differential input port with INLO.
Low Signal Input Terminal. Part of a differential input port with INHI.
Disable/Enable Control Input. Apply logic high voltage to shut down the AD8362.
Connection for loop filter integration (averaging) capacitor, the other pin of which is usually
grounded via a resistor to improve loop stability and response time.
Analog Common Connection for Output Amplifier.
The voltage applied to this pin sets the decibel value of the required RF input voltage that results in
zero current out of CLPF and thus the loop integrating capacitor.
Output of Error Amplifier. In measurement mode, 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.
General-Purpose Reference Voltage Output of 1.25 V (usually connected only to VTGT).
