NOTES: (1) The single-ended input range is set by REFB and REFT values. (2) dBFS means dB relative to Full Scale. (3) Effective number of bits (ENOB) is defined
by (SINAD – 1.76)/6.02. (4) Offset deviation from ideal negative full scale.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
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.
