Note 1:
DC parameters are tested at +25°C, and guaranteed by design and characterization at -40°C and +85°C.
Note 2:
Maximum difference between frequency response at any point and a straight line connecting frequency response at
end points.
Note 3:
Gain control stability is the maximum variation in transimpedance (over process, voltage, and temperature) for any V
AGC
control voltage.
Note 4:
AC parameters guaranteed by design and characterization.
Note 5:

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
