NOTES: (1) LSB means Least Significant Bit. For the ±10V input range, one LSB is 305µV. (2) Typical rms noise at worst case transitions and temperatures. (3)
As measured with fixed resistors shown in Figure 4. Adjustable to zero with external potentiometer. (4) For bipolar input ranges, full scale error is the worst case
of –Full Scale or +Full Scale untrimmed deviation from ideal first and last code transitions, divided by the transition voltage (not divided by the full-scale range) and
includes the effect of offset error. For unipolar input ranges, full scale error is the deviation of the last code transition divided by the transition voltage. It also includes
the effect of offset error. (5) All specifications in dB are referred to a full-scale ±10V input. (6) Full-Power Bandwidth defined as Full-Scale input frequency at which
Signal-to-(Noise+Distortion) degrades to 60dB. (7) Recovers to specified performance after 2 x FS input overvoltage.

ESD damage can range from subtle performance degrada-
tion 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.
