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.
