Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its specified operating ratings. Operating Ratings indicate conditions for which the device is functional, but do not guarantee performance limits.
For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some per-
formance characteristics may degrade when the device is not operated under the listed test conditions.
Note 2: All voltages are measured with respect to the GND pin, unless otherwise specified.
Note 3: When the input voltage (VIN) at any pin exceeds the power supply voltage (VIN < GND or VIN > V+), the absolute value of the current at that pin should be
limited to 5 mA or less. The 20 mA package input current specification limits the number of pins that can exceed the power supply boundaries with a 5 mA current
limit to four.
Note 4: The power dissipation of this device under normal operation should never exceed 875 mW (Quiescent Power Dissipation + the loads on the digital outputs).
Caution should be taken not to exceed absolute maximum power rating when the device is operating in a severe fault condition (e.g., when any input or output ex-
ceeds the power supply). The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX (maximum junction temperature), θJA
(package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJMAX
− TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. The table below details TJMAX and θJA for the various packages and versions
of the ADC08061/2.

Note 5: See AN-450 “Surface Mounting Methods and Their Effect on Product Reliability” for other methods of soldering surface mount devices.
Note 6: Human body model, 100 pF discharged through a 1.5 kresistor.
Note 7: Typicals are at 25˚C and represent most likely parametric norm.
