5 / 41 page I/O GND TO INTERNAL CIRCUITRY ADC081C021, ADC081C027 www.ti.com SNAS447C – FEBRUARY 2008 – REVISED MARCH 2013 Absolute Maximum Ratings (1) (2) (3) Supply Voltage, VA (4) -0.3V to +6.5V Voltage on any Analog Input Pin to GND −0.3V to (VA +0.3V) Voltage on any Digital Input Pin to GND −0.3V to 6.5V Input Current at Any Pin(5) ±15 mA Package Input Current(5) ±20 mA Power Dissipation at TA = 25°C See(6) Human Body Model 2500V VA, GND, VIN, ALERT, ADR pins Machine Model 250V ESD Susceptibility(7) Charged Device Model (CDM) 1250V Human Body Model 8000V SDA, SCL pins Machine Model 400V Junction Temperature +150°C Storage Temperature −65°C to +150°C (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 ensure specific performance limits. For ensured specifications and test conditions, see the 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. Operation of the device beyond the maximum Operating Ratings is not recommended. (2) All voltages are measured with respect to GND = 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) To ensure accuracy, it is required that VA be well bypassed and free of noise. (5) When the input voltage at any pin exceeds 5.5V or is less than GND, the current at that pin should be limited per the Absolute Maximum Ratings. The maximum package input current rating limits the number of pins that can safely exceed the power supplies. (6) The absolute maximum junction temperature (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 will be reached only when the device is operated in a severe fault condition (e.g., when input or output pins are driven beyond the operating ratings, or the power supply polarity is reversed). (7) Human body model is a 100 pF capacitor discharged through a 1.5 k Ω resistor. Machine model is a 220 pF capacitor discharged through 0 Ω. Charged device model simulates a pin slowly acquiring charge (such as from a device sliding down the feeder in an automated assembler) then rapidly being discharged. Operating Ratings (1) (2) Operating Temperature Range −40°C ≤ TA ≤ +105°C Supply Voltage, VA +2.7V to 5.5V Analog Input Voltage, VIN 0V to VA Digital Input Voltage(3) 0V to 5.5V Sample Rate up to 188.9 ksps (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 ensure specific performance limits. For ensured specifications and test conditions, see the 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. Operation of the device beyond the maximum Operating Ratings is not recommended. (2) All voltages are measured with respect to GND = 0V, unless otherwise specified. (3) The inputs are protected as shown below. Input voltage magnitudes up to 5.5V, regardless of VA, will not cause errors in the conversion result. For example, if VA is 3V, the digital input pins can be driven with a 5V logic device.
