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
AD8304 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.

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 affect device reliability.

. This
pin is usually grounded; for details of
usage, see Applications section.
Power-Down Control Input. Device is
active when PWDN is taken LOW.
Guard Pins. Used to shield the INPT
current line.
Photodiode Current Input. Usually
connected to photodiode anode (the
photo current flows toward INPT).
Photodiode Biaser Output. May be
connected to photodiode cathode to
provide adaptive bias control.
