3 / 25 page ADC121S051 www.ti.com SNAS302I – JULY 2005 – REVISED JANUARY 2014 Absolute Maximum Ratings (1) (2) (3) Analog Supply Voltage VA −0.3V to 6.5V Voltage on Any Digital Pin to GND −0.3V to 6.5V Voltage on Any Analog Pin to GND −0.3V to (VA +0.3V) Input Current at Any Pin (4) ±10 mA Package Input Current (4) ±20 mA Power Consumption at TA = 25°C See (5) ESD Susceptibility (6) Human Body Model 3500V Machine Model 300V 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. (2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications. (3) All voltages are measured with respect to GND = 0V, unless otherwise specified. (4) When the input voltage at any pin exceeds the power supply (that is, VIN < GND or VIN > VA), the current at that pin should be limited to 10 mA. The 20 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 two. The Absolute Maximum Rating specification does not apply to the VA pin. The current into the VA pin is limited by the Analog Supply Voltage specification. (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 device 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. Operating Ratings (1) (2) Operating Temperature Range −40°C ≤ TA ≤ +85°C VA Supply Voltage +2.7V to +5.25V Digital Input Pins Voltage Range −0.3V to +5.25V (regardless of supply voltage) Analog Input Pins Voltage Range 0V to VA Clock Frequency 25 kHz to 20 MHz Sample Rate up to 1Msps (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. (2) All voltages are measured with respect to GND = 0V, unless otherwise specified. Package Thermal Resistance (1) Package θJA 6-lead WSON 94°C / W 6-lead SOT-23 265°C / W Soldering process must comply with Reflow Temperature Profile specifications. Refer to www.ti.com and http://www.ti.com/lit/SNOA549. (1) Reflow temperature profiles are different for lead-free and non-lead-free packages.
