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.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not
apply when operating the device beyond its specified operating conditions.
(2) All voltages are measured with respect to GND, unless otherwise specified.
(3) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.
(4) A Zener diode exists, internally, from V

(1) Total unadjusted error includes offset, full-scale, linearity, and multiplexer errors. See Figure 5. None of these A/Ds requires a zero or
full-scale adjust. However, if an all zero code is desired for an analog input other than 0.0V, or if a narrow full-scale span exists (for
example: 0.5V to 4.5V full-scale) the reference voltages can be adjusted to achieve this. See Figure 15.
