3 / 26 page ADC128S052 www.ti.com SNAS333C – AUGUST 2005 – REVISED NOVEMBER 2010 Absolute Maximum Ratings (1) Analog Supply Voltage VA −0.3V to 6.5V Digital Supply Voltage VD −0.3V to VA + 0.3V, max 6.5V Voltage on Any Pin to GND −0.3V to VA +0.3V Input Current at Any Pin (2) ±10 mA Package Input Current(2) ±20 mA Power Dissipation at TA = 25°C See (3) ESD Susceptibility (4) Human Body Model 2500V Machine Model 250V For soldering specifications: see product folder at www.national.com and www.national.com/ms/MS/MS-SOLDERING.pdf 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 guarantee specific performance limits. For guaranteed specifications and test conditions, see the ADC128S052 Converter Electrical Characteristics, Note 1. 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. (2) 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 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. (3) 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. In the 16-pin TSSOP, θJA is 96°C/W, so PDMAX = 1,200 mW at 25°C and 625 mW at the maximum operating ambient temperature of 105°C. Note that the power consumption of this device under normal operation is a maximum of 12 mW. The values for maximum power dissipation listed above will be reached only when the ADC128S052 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. (4) 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 ADC128S052 −40°C ≤ TA ≤ +105°C ADC128S052Q −40°C ≤ TA ≤ +125°C VA Supply Voltage +2.7V to +5.25V VD Supply Voltage +2.7V to VA Digital Input Voltage 0V to VA Analog Input Voltage 0V to VA Clock Frequency 50 kHz to 16 MHz (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 ADC128S052 Converter Electrical Characteristics, Note 1. 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. (2) All voltages are measured with respect to GND = 0V, unless otherwise specified.
