2 / 31 page ABSOLUTE MAXIMUM RATINGS (1) ADS5270 SBAS293F – JANUARY 2004 – REVISED JANUARY 2009............................................................................................................................................... www.ti.com This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(2) Thermal pad size: 4.69mm × 4.69mm (min), 6.20mm × 6.20mm (max). Supply Voltage Range, AVDD –0.3V to +3.8V Supply Voltage Range, LVDD –0.3V to +3.8V Voltage Between AVSS and LVSS –0.3V to +0.3V Voltage Between AVDD and LVDD –0.3V to +0.3V Voltages Applied to External REF Pins –0.3V to +2.4V All LVDS Data and Clock Outputs –0.3V to +2.4V Analog Input Pins(2) –0.3V to min. [3.3V, (AVDD + 0.3V)] Digital Input Pins, Set 1 (pins 69, 76-78) –0.3V to min. [3.9V, (AVDD + 0.3V)](3) Digital Input Pins, Set 2 (pins 16, 45) –0.3V to min. [3.9V, (LVDD + 0.3V)](3) Operating Free-Air Temperature Range, TA –40°C to +85°C Lead Temperature, 1.6mm (1/16" from case for 10s) +260°C Junction Temperature +105°C Storage Temperature Range –65°C to +150°C (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those specified is not supported. (2) The dc voltage applied on the input pins should not go below –0.3V. Also, the dc voltage should be limited to the lower of either 3.3V or (AVDD + 0.3V). If the input can go higher than +3.3V, then a resistor greater than or equal to 25 Ω should be added in series with each of the input pins. Also, the duty cycle of the overshoot beyond +3.3V should be limited. The overshoot duty cycle can be defined either as a percentage of the time of overshoot over a clock period, or over the entire device lifetime. For a peak voltage between +3.3V and +3.5V, a duty cycle up to 10% is acceptable. For a peak voltage between +3.5V and +3.7V, the overshoot duty cycle should not exceed 1%. Any overshoot beyond +3.7V should be restricted to less than 0.1% duty cycle, and never exceed +3.9V. (3) It is recommended to use a series resistor of 1k Ω or greater if the digital input pins are tied to AVDD or LVDD supplies. 2 Submit Documentation Feedback Copyright © 2004–2009, Texas Instruments Incorporated Product Folder Link(s): ADS5270 |
