SBAS295A – JULY 2004 – REVISED JANUARY 2007

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.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to absolute

maximum conditions for extended periods may affect device reliability.

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.
