Description

1

FLTR

Modulation Filter Pin. Connection for an External Capacitor to lower the corner frequency of the modulation filter

2

VPOS

Supply Voltage Pin. Operational range 2.7 V to 3.5 V.

3

RFIN

Signal Input Pin. Internally ac-coupled after internal termination resistance. Nominal 500 Ω input impedance.

4

COMM

Device Ground Pin.

5

PK/ENV

mode. Reset peak-hold by placing device in real-time envelope measurement mode.

6

VPK/ENV

Envelop Output. Function can switched between real-time envelop measurement or peak-hold using PK/ENV.

7

VRMS

RMS Output Pin. Rail-to-rail voltage output with limited current drive capability. The output has an internal TBD kΩ

series resistance. High resistive loads are recommended to preserve output swing.
