ABSOLUTE MAXIMUM RATINGS

RECOMMENDED OPERATING CONDITIONS

ADS5500

SBAS303F – DECEMBER 2003 – REVISED FEBRUARY 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 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 implied.

(2)

If the input signal can exceed 3.6 V, then a resistor greater than or equal to 25

Ω should be added in series with each of the analog

input pins to support input voltages up to 3.8 V. For input voltages above 3.8 V, the device can only handle transients and the duty cycle

of the overshoot should be limited to less than 5% for inputs up to 3.9 V.
