7 / 43 page ADC08D502 www.ti.com SNOSC85 – AUGUST 2012 Pin Functions Pin No. Symbol Equivalent Circuit Description 40, 51 ,62, 73, 88, 99, VDR Output Driver power supply pins. Bypass these pins to DR GND. 110, 121 1, 6, 9, 12, 21, 24, 27, GND Ground return for VA. 41 42, 53, 64, 74, 87, 97, DR GND Ground return for VDR. 108, 119 52, 63, 98, NC No Connection. Make no connection to these pins. 109, 120 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 (1) (2) Supply Voltage (VA, VDR) 2.2V Supply Difference VDR - VA 0V to 100 mV Voltage on Any Input Pin (Except VIN+, VIN- ) −0.15V to (VA +0.15V) Voltage on VIN+, VIN- (Maintaining Common Mode) -0.15V to 2.5V Ground Difference |GND - DR GND| 0V to 100 mV Input Current at Any Pin (3) ±25 mA Package Input Current (3) ±50 mA Power Dissipation at TA = 85°C 2.0 W ESD Susceptibility (4) Human Body Model 2500V Machine Model 250V Soldering Temperature, Infrared, 10 seconds (5) 235°C Storage Temperature −65°C to +150°C (1) All voltages are measured with respect to GND = DR GND = 0V, unless otherwise specified. (2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. There is no guarantee of operation at the Absolute Maximum Ratings. 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 Electrical Characteristics. 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. (3) When the input voltage at any pin exceeds the power supply limits (that is, less than GND or greater than VA), 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. This limit is not placed upon the power, ground and digital output pins. (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. (5) See AN-450, “Surface Mounting Methods and Their Effect on Product Reliability”. Operating Ratings (1) (2) Ambient Temperature Range −40°C ≤ TA ≤ +85°C Supply Voltage (VA) +1.8V to +2.0V Driver Supply Voltage (VDR) +1.8V to VA (1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. There is no guarantee of operation at the Absolute Maximum Ratings. 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 Electrical Characteristics. 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.
