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. (2) All voltages are measured with respect to GND = 0V, unless otherwise specified. (3) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications. (4) When the input voltage at any pin exceeds the power supplies (that is, VIN < AGND or VIN > VA or VD), the current at that pin should be limited to 10 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 10 mA to five. (5) 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 listed above will be reached only when the ADC121S625 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 1.5 k Ω resistor. Machine model is 220 pF discharged through ZERO ohms. (7) See AN450, “Surface Mounting Methods and Their Effect on Product Reliability”, or the section entitled “Surface Mount” found in any post 1986 Texas Instruments Linear Data Book, for other methods of soldering surface mount devices. Operating Ratings (1) (2) Operating Temperature Range −40°C ≤ TA ≤ +85°C Supply Voltage, VA +4.5V to +5.5V Reference Voltage, VREF +0.1V to 2.5V Input Common-Mode Voltage, VCM See Figure 51 Digital Input Pins Voltage Range 0 to VA Clock Frequency 0.8 MHz to 3.2 MHz Differential Analog Input Voltage −VREF to +VREF (1) Absolute maximum ratings are limiting values which indicate limits beyond which damage to the device may occur.
