*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may effect device reliability.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD8307 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.

1
INM Signal Input, Minus Polarity; Normally at
VPOS/2.
2
COM Common Pin (Usually Grounded).
3
OFS Offset Adjustment; External Capacitor
Connection.
4
OUT Logarithmic (RSSI) Output Voltage; ROUT =
12.5 kΩ.
5
INT Intercept Adjustment; ± 6 dB (See Text).
6
ENB CMOS-compatible Chip Enable; Active when
“HI.”
7
VPS Positive Supply, 2.7 V–5.5 V.
8
INP Signal Input, Plus Polarity; Normally at VPOS/
2. Note: Due to the symmetrical nature of the
response, there is no special significance to the
sign of the two input pins. DC resistance from
INP to INM = 1.1 kΩ.
