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 = AV
Note 3: When the input voltage at any pin exceeds the power supplies (that is, less than AV
should be limited to 25 mA. The 50 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input
current of 25 mA to two.
Note 4: The absolute maximum junction temperatures (T
junction-to-ambient thermal resistance θ
for maximum power dissipation listed above will be reached only when the ADC1175 is operated in a severe fault condition (e.g. when input or output pins are
driven beyond the power supply voltages, or the power supply polarity is reversed). Obviously, such conditions should always be avoided.
Note 5: Human body model is 100 pF capacitor discharged through a 1.5kΩ resistor. Machine model is 220 pF discharged through ZERO Ω.
Note 6: See AN–450, "Surface Mounting Methods and Their Effect on Product Reliability", or the section entitled "Surface Mount" found in any post 1986 National
Semiconductor Linear Data Book, for other methods of soldering surface mount devices.
Note 7: The analog inputs are protected as shown below. Input voltage magnitudes up to 6.5V or to 500 mV below GND will not damage this device. However,
errors in the A/D conversion can occur if the input goes above V

Note 10: At least two clock cycles must be presented to the ADC1175 after power up. See Section 4.0 for details.
