SNAS012H – JANUARY 2000 – REVISED APRIL 2013

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

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 ensure specific performance limits. For ensured specifications and test conditions, see

CONVERTER ELECTRICAL CHARACTERISTICS. The ensured specifications apply only for the test conditions listed. Some

performance characteristics may degrade when the device is not operated under the listed test conditions.

(2)

All voltages are measured with respect to GND = AVSS = DVSS = 0V, unless otherwise specified.

(3)

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and

specifications.

(4)

When the input voltage at any pin exceeds the power supplies (that is, less than AVSS or DVSS, or greater than AVDD or DVDD), the

current at that pin 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.

(5)

The absolute maximum junction temperatures (TJmax) for this device is 150°C. The maximum allowable power dissipation is dictated by

TJmax, the junction-to-ambient thermal resistance θJA, and the ambient temperature, TA, and can be calculated using the formula

PDMAX = (TJmax - TA )/θJA. The values 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.

(6)

Human body model is 100 pF capacitor discharged through a 1.5k

Ω resistor. Machine model is 220 pF discharged through ZERO Ω.
