NOTES
1Absolute maximum ratings are limiting values, to be applied individually, and
beyond which serviceability may be impaired. Functional operation under any of
these conditions is not necessarily implied.
2CAL OUT should drive a single TTL or CMOS input.
3Typical Thermal Impedance:
28-lead SOIC (plastic)
θ
JA = 71.4 °C/W; θJC = 23°C/W.
4When soldering surface mount packages in vapor phase equipment, temperature
should not exceed 220
°C for more than one minute.

WARNING!
ESD SENSITIVE DEVICE
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 AD9561 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.
