Pin Functions

PIN TYPE DESCRIPTION
NUMBER NAME
A1 VDD Power Supply Positive supply voltage.
A2 OUT Output Ground referenced detector output voltage.
B1 RFIN Analog Input RF input signal to the detector, internally terminated with 50 Ω.
B2 GND Power Supply Power Ground. May be left floating in case grounding is not feasible.
C1 GND Power Supply Power Ground.
C2 EN Logic Input The device is enabled for EN = High, and in shutdown mode for EN = Low. EN must be < 2.5 V to have low IEN. For EN > 2.5 V, IEN increases slightly, while device is still functional. Absolute maximum rating for EN = 3.6 V.
