AD648
NOTES
1
Input Offset Voltage specifications are guaranteed after 5 minutes of operation at T
A
= +25°C.
2
Bias Current specifications are guaranteed maximum at either input after 5 minutes of operation at T
A
= +25°C. For higher temperature, the current doubles
every 10°C.
3
Matching is defined as the difference between parameters of the two amplifiers.
4
Defined as voltages between inputs, such that neither exceeds
±
10 V from ground.
Specifications subject to change without notice.

NOTES
1
Stresses above those listed under “Absolute Maximum Ratings” may cause
permanent damage to the device. This is a stress rating only and 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 AD648 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.
