1
VRMS
Output Pin. Rail-to-rail voltage output with limited current drive capability. The output has an internal 1 kΩ
series resistance. High resistive loads are recommended to preserve output swing.
2
COMM
Device Ground Pin.
3
RFIN
Signal Input Pin. Internally ac-coupled after internal termination resistance. Nominal 50 Ω input impedance.
4
VPOS
Supply Voltage Pin. Operational range 2.7 V to 5.5 V.
