• Manufacturer: NSC [National Semiconductor]

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is functional,
but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply
only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.
Note 2: All voltages are measured with respect to GND=AGND=DGND=0V, unless otherwise specified.
Note 3: When the input voltage (V
imum package input current rating limits the number of pins that can simultaneously safely exceed the power supplies with an input current of 25mA to two.
Note 4: The maximum power dissipation must be derated at elevated temperatures and is dictated by T
able power dissipation at any temperature is P
is 69°C/W for the M28B SOIC package
Note 5: Human body model, 100pF capacitor discharged through a 1.5k
Note 6: See AN450 “Surface Mounting Methods and Their Effect on Product Reliability” or the section titled “Surface Mount” found in any National Semiconductor Linear
Data Book for other methods of soldering surface mount devices.
