PRODUCT DESCRIPTION
The AD8361 is a mean-responding power detector for use in high-
frequency receiver and transmitter signal chains, up to 2.5GHz.
It is very easy to apply. It requires only a single supply between
2.7 V and 5.5 V, power supply decoupling capacitor and an
input coupling capacitor in most applications. The output is a
linear-responding dc voltage with a conversion gain of 7.5 V/Vrms.
An external filter capacitor can be added to increase the averag-
ing time constant.

The AD8361 is intended for true power measurement of simple
and complex waveforms. The device is particularly useful for
measuring high crest-factor (high peak-to-rms ratio) signals, such
as CDMA and W-CDMA.
The AD8361 has three operating modes to accommodate a
variety of analog-to-digital converter requirements:
1. Ground referenced mode, in which the origin is zero;
2. Internal reference mode, which offsets the output 350 mV
above ground;
3. Supply reference mode, which offsets the output to V
S
/7.5.
The AD8361 is speci
fi
ed for operation from
–
40
°
C to +85
°
C and
is available in 8-lead micro_SOIC and 6-lead SOT packages.
It is fabricated on a proprietary high f
T
silicon bipolar process.
