Pin No. Mnemonic Description
1
FLTR
Modulation Filter. Connect an external capacitor to this pin to lower the corner frequency of the modulation filter.
2
VPOS
Supply Voltage. The operational range is 2.5 V to 3.3 V.
3
RFIN
Signal Input. This pin is internally ac-coupled after internal termination resistance. The nominal input impedance
is 500 Ω.
4
COMM
Device Ground.
5
VRMS
RMS Output. This pin is a rail-to-rail voltage output with limited current drive capability. The output has an internal
100 Ω series resistance. High resistive loads and low capacitance loads are recommended to preserve output swing
and allow fast response.
6
ENBL
Enable. Connect this pin to VS for normal operation. Connect this pin to ground for disable mode.
