*Stresses above those listed under Absolute Maximum Ratings may cause permanent

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 affect 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 AD8314 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.

WARNING!

Pin Function Descriptions

Pin

Name

Function

1

RFIN

RF Input.

2

ENBL

Connect pin to ground for disable mode.

3

VSET

Setpoint input for operation in controller

mode. To operate in detector mode connect

VSET to V_UP

4

FLTR

Connection for an external capacitor to slow

the response of the output. Capacitor is con-

nected between FLTR and V_UP.

5

COMM

Device Common (Ground).

6

V_UP

Logarithmic output. Output voltage increases

with increasing input amplitude.

7

V_DN

Inversion of V_UP, governed by the following

equation: V_DN = 2.25 V – 2

× V
