Description
RF Input.
Connect Pin to V
S
for Normal Operation. Connect pin to ground for disable mode.
Setpoint Input for Operation in Controller Mode. To operate in detector mode connect VSET to V_UP.
Connection for an External Capacitor to Slow the Response of the Output. Capacitor is connected between
FLTR and V_UP.
Device Common (Ground)
Logarithmic Output. Output voltage increases with increasing input amplitude.
Inversion of V_UP, Governed by: V_DN = 2.25 V − 2 × V
